All together I spent about $40 - $50 bucks, finding most materials from what I had in my garage or around the home.
Things you'll need:
- Hot Glue Gun (and sticks - the bigger the bag the better)
- Duct Tape (Red, Gray)
- Masking Tap (Mainly for paint)
- Small Ruler and Big Ruler
- Exacto Blade
- Scissors
- Spray Paints (Primer, Red, Blue, white and Mettalic)
- $.99 cents store Mini Flashlights (4 of them)
- Hard HAt (about $6.00 at any Hardware Store)
- Velcro (Found at Major stores like Target, Kmart etc.)
- Lots and lots of cardboard, or foam board. Most companies throw out scrap or just go to your local markets and ask them to save you some before tossing.
- 2 tin cans (emptied of course)
- 2 plastic report sheet covers (for the windshields)
- I used old Hockey Gloves but any cheap canvas ones will work.
- Packaging tubes or PVC piping
Over the last month I've found myself staring at piles of trash while driving, hoping to find something I can use for my costume. Always try to be frugal and inventive.
Step 1: Creating the head
First select an old bicycle, snowboarding, or hardhat helmet that you never plan on using again.
From the Cardboard or foamboard
- Cut 2 ear flaps (Triangle shape)
- Cut 1 center unit piece (Retangle Shape)
- Cut 2 side discs where you plan on attaching the 2 antennae. (circle discs) Antennae.
Like most of this project it will be a series of trial and error to make things fit, the ear flaps are no exception. Once you have your desired shapes cut out, you'll need to cut circles on the inside to affix to the helmet with hot glue. Adjust fast because the glue dries quick.
The Center unit will present the biggest challenge as the concave center will need to be cut out with your best estimate then refitted for additional cuts. Remember don't over guess because you can always take off more, but you can't regrow once cut. Take your time on this fitting, it will pay off in the end.
Finally as for the side discs, just cut out 4 identical round discs, then for interior spacing take small scraps of cardboard and stack them like pancakes. Identical in number so both discs are even. Sandwich the small scraps with 2 discs and glue in place. Wrap then glue with out rim with a thin strip that covers the sandwich space. While drying cut out 2 long strips which will be the antannae (equal length) then measure out there width on the strip part of the disc. Cut slats on the discs just big enough to fit the antannae then put some glue on the tips and insert in the hold. Attach to the outer flaps and you've got an Optimus helmet.
Prepare for Painting by taping open areas of fabric with masking tape and any plastic bags around the home. Primer first, then paint over with the blue color of your liking.
Step 2:
I cut out a cross shape on it about the size of a regular sheet of paper (8" x 11-1/2") then folded and hot glued the edges together. Again the better your measurements and cuts in the beginning the better your final project will look.
I cut 1 center line the same length as the longest side (11-1/2") and hot glued it to the center.
I then measured and cut out 16 equal slats, slight taller than the interior depth because I planned on slanting them. Carefully I glued each slat into place, visually trying to adjust them to the same angle slant. (Trust me your hands become more skilled as you do this.)
Luckily foam board doesn't require primer as it is almost alwasys ready for paint.
Step 3: The Chest Piece
Take a box, slide it over your body like a sock and guess how much needs to be cut to fit perfectly around your chest without counting your arms into the space. Cut out 2 big holes on the sides and try it on again. Most times your guess will be spot and won't need redoing.
Cut a vertical opening in the back so you can enter and exit easily.
Close off the top and cut out a big head hole. (Cut it a little larger than your head so your shoulder/neck muscles will fit through it better. (You may notice that while a box is perfectly happy to have all 90 degree angles, our shoulders aren't built that way. The have a little bit of a downward "V" shape)
Duct tape all interior bends. This reinforcement will become invaluable as you work the suit and tears begin to reveal themselves.
Step 4: Adding comfort and detail to chest
I put 2 strips and tried sewing them in for reinforcement but found the needles couldn't hold up so I hot glued them. If you can get any sewing in I recommend it highly as sometimes the glue tends to rip off the first layer of cardboard.
Here I've added an awning flap where I plan on putting the small flashlights I bought at the 99 cents store.
Step 5: Painting the chest piece
Here I've set up the chest piece and small flashlights for paint. (Apple red of course)
Try to save your paint by knowing ahead of time what will be showing and what will be covered by other parts. As you can see i didn't paint the front slats in the chest piece becuase I knew I would addint windshield pieces later.
Conserving your paint with bring the dollar value on your expenditures down, so don't paint the inside please; that would just be ridiculous.
Step 6: Chest piece detail and flare
*word to the wise, if paint is not completely dry, the hot glue will melt the paint and make the bond weak, meaning a.) You'll have to repaint, and b.) Your glue won't stick. So wait until it's dry for sure.
I cut out 2 windshield slats to slide into the chest openings then paint them sky blue. The lighting bolts you see were cut out of regular white print paper then Elmers glued into place. I then took 2 plastic sheets found on those report covers I used to hand in to school, and cut then glued them over the blue sky and lighting bolts. This will give you that glass reflective look without actually have glass.
Hot glue them into the covering and if you want create an outer frame for them by painting metalic foam board strips and hot glueing them to the outer edges.
As you may also notice I painted the bottom of the fram metalic by masking off the top portion with tape and plastic bags found around the house.
*Side note: Notice Spaceballs is on the TV in the background!
Step 7: Torso coming together
1-Head
2-Chest
3-Torso
I kept the lower torso separate from the upper chest portion and similar to the chest piece I opened up the back of the lower torso and used velcro as the clasp. Think of it as a girdle of sorts. adjusting to whatever weight or body types needed. It's pretty much a box that's open on top and bottom. I double walled this torso because I knew it would have to survive multiple attempts at sitting.
I made it slightly thinner than the upper torso so it could slide into it when I sit down, like an accordion. I also added a pair of suspendors to the inside to help with the weight and to keep it from sliding down.
Step 8: My two left feet
- Decide on how big you want the feet and create the box+trapazoid design you want.
- Cut out 8 to 12 pieces out of the foam and hot glue together on a pancake stack.
- Save just enough foam for the top layer where you will trace out a silouette of the bottom of your sneaker.
- You will cut out that silouette and put the shoe in. This will keep your shoe from sliding back and forth inside.
- Hot glue a velcro strap around all the foam pieces so that it meets just above the shoe. This will hold the shoe down into the silouette and give you more stability.
- Now build the shell around the foot and for added strength, insert some screws into the foam through the cardboard.
- When you paint make sure the shoes aren't inside the boxes!
Step 9: Creating the legs
Measure the length of your leg and go about 4 to 5 inches above the knee. Remember you can always cut away more, but your can't regrow cardboard.
Add strength and durability to the pieces by affixing duct tape to the interior bends. Again this will help with tears.
Fit the bottom opening to the feet and cut as needed. Double wall whenever time, energy and cardboard allow. It will help in the long run, but it does make the outfit a little heavier.
Step 10: Getting them feet to dance
I added velcro strap to the top of the legs that attach just behind the knee. With the lower half hugging the outside of the feet and the top half held against my knee you'll find it very stable and comfortable.
I also began making the design for the front of the lower leg where the vents will be places.
Step 11: Completing the lower leg & Paint
If you can't find any, and need to create some. Then see step 1 about creating discs. Same procedure different paint.
For Gas Cannisters I used old Tin Cans and painted them the same metalic as the other parts.
*Special note: Bolt these wheels and tin can to the leg piece. Just using glue is not enough. They will be knocked off. Make sure you use washers whenever bolting anything to cardboard. This will held secure it better by not punching holes in your creation.
Use the same technique for creating front vents that you used for creating the stomach grill. Foamboard works great.
Step 12: New Helmet needed
I purchased a HArd Hat at home depot for $7 bucks, pulled off the straps (becuase they raise the helmet off your head too much and hot glued some padding in it, I ripped off an old bicycle helmet.
the reuslts were much, much better.
I made the sides thinnner and reused the side flaps and antannae from the first helmet. I recommend this one instead of using a snowboard helmet!
The face shield was cut then painted metalic to match the other parts of the costume. It's removable and held in place by 2 small pieces of velcro on the inside. I plan on purchasing a pair of blue tinted sun glasses to wear underneath as I've already got severe tunnel vision in this helmet and don't need to further reduce my line of sight.
Don't forget... PRIMER THEN PAINT!!! IT'S A MUST!!!
Step 13: Almost finished
The arms are basically 3 boxes.
- The shoulders were originally loose but then I decided the weight was too much and they began to sag (droopy optimus) so I attached them to the chest piece, which made it difficult to get in and out of, so I made the front of them flaps that open up like garage doors. When not open they're held shut by 2 small pieces of velcro straps on each interior side. Unless someone undoes them, they hold pretty well. (Hot glue of course)
- The exhaust pipes are from onld packaging material. Fabric stores have these and toss them. The're thicker than toilet rolls and stronger than Bounty roll tubes. I recommend they be sturdy as I plan on having them tugged at all night long on Halloween. They, like the tires on the legs, are bolted on. Again to prevent shearing. The holes are painted on using label stickers. I firts painted the lower half black. Waited for it to dry; placed the stickers evenly apart, then painted over them with the metalic spray paint. after drying I simple peeled off the stickers carefully with a pair of tweezers. You'll notice I shaded the tops to make them appear used.
Step 14: Arms & Side Wheels
The waist piece is just some rubber foam matting I found at Target for $1.24 in the clearance section. I added the raised yellow pieces by cutting them out and wrapping them in bright yellow duct tape.
The thigh pieces both open in the back and are free standing. They have overlaping velcro closures and are reinforced by straps I found on an old baby front back pack. The velcro wasn't enough, as they would open when I tried to sit, so adding these straps was very helpful in keeping them closed. The design is just lines and dots, although I did add some shading on the outside to make it look more industrial.
As for the Arms, I was lucky that my Garage Junk included a Polycentric Hinge that I used to stabilize the upper and lower arms. See the attached design to help you visualize how the arms were created. Let me know if you have any more questions on the arms and some of the small details.
Step 15:
They look more robotic, have more padding so the cardboard doesn't dig into your wrist and just fit the overall dimensions of the suit better.
Unfortunately the material does not lend itself to being painted, so I had to apply about 6 coats becuase each one kept being absorbed over and over again until finally it held. I have no remedy of this, just some advise to make you you save an entire paint can for just this.
Step 16:
Now If only can remember where my bed is. It's been so long that I might have trouble finding it.
Step 17:
1.) Your home is going to be an absolute mess. If your wife has problems with little messes, then she's going to freak out and problably going to want a divorce before this is over. Try and clean up as you go along. It will definitely get knee deep in trash. Also cover any important wood you'll be working on with layers of extra cardboard. You'll be digging into it with your Xacto knife if you're not careful.
2.) Set an area aside in your home where you can place the completed pieces. Preferably out of foot traffic or where the dog will pee on it. This costume takes up a lot of space so make sure you don't damage your hard work. Also pre-plan how and where you intend to store the costume once completed. Luckily I have a garage and lots of packing material. If your single it could become permanent art in your room, but if you have a girlfriend or spouse these things are not possible, as they will clash with the Pottery Barn theme she is working toward.
All in all I have to say it's been one of the most rewarding expiriences. Lot's of time and love went into it. I hope you can find or commit the same amount when creating yours. I leave you with 3 bits of advice:
1.) Learn the interior fold for cleaner lines.
2.) Duct tape all bends for reinforcement
3.) Learn to work on 3 to 4 hours of sleep a night.
Godspeed and good luck

My three year old wanted to be Optimus prime for halloween so I had to scale the costume down quite a bit. Thanks for the good design Idea!! He loved it and the family was impressed with what you can do with some cardboard and a bunch of hot glue:)
Unfortunately it wasn't finished, still needed a few touches here and there, but still went down a great hit.
Thanks again!
Doorstop
I took on the challange of doing my own Prime using our Prime as a blue print. I wore it last weekend for our pop culture expo, Supanova in Sydney, Australia. I could only wear it for a short time but when I did have it on, I could not move without everyone stopping me for a pic.
Took me over 2 1/2 months to make and had to cram in the time in the end to get it done. Still needs a bit of work done but the result was epic!!
Thanks for the blue prints. Without them I don't think I would of got this done. The pic's are a shorten pic history. Enjoy.
Just a warning for other Primes-to-be out there: I did have a problem with several of the kids thinking I was a Real Steel robot and trying to get me to fight by hitting or kicking me. The parents usually told them to stop but after a while I had to find a buddy to try and stop them before they got close enough to hit. (For most of them you can tell which ones are going to hit you but they're really smart about coming in from your blind sides.) After spending hours and hours working on this costume it was extremely frustrating having it get banged and torn up. Be sure and bring along repair supplies if there's going to be kids around.
Tips would be nice
Dimensions
Anything that you could give us so that we can have an easier time building it. Thanks man, your great.
"ummmm, mommy, I think I want to be a Decepticon instead..." Honestly! The little monster. LOL.
Once he put it on though, he was so psyched to be Optimus. I think he was just yanking my chain.
Here's a pic of our finished product at the end of our night.
I had to make some adjustments to accomodate a child, like making it lighter... waaayyyy lighter.
For the shoes I only made the front halves and had them hinge directly onto the leg, so the shoe and leg were one big piece.
The leg pieces I cut at an angle at the bottom to accomodate a natural stepping motion. Worn with light up shoes it actually added to the costume.
I reinforced the folds on the inside with a finger swipe of caulk and it made the costume super sturdy on the folds.
My windows were cut from an old calendar.
I left out the sides of the torso because it added to much bulk to such a small frame. This really made it easy to slip on and off and because of the arm pieces you can't even tell the sides are missing.
The shoulders are attached with tiny hinges so they move up whenever my son lifts his arms outward.
### One thing I would do differently and something I would recommend for anyone making a costume like this for a small child is to make a template of the entire costume out of a very lightweight cardboard like a cereal box.
Before you glue any of it together, trace and cut out the same pattern out of Foamies (pictured below)
You can find Foamies by the roll (36" by 60") at craft stores like JoAnn Fabrics, Michaels, and Hobby Lobby for about $5 when it's on sale or you use a coupon. Just buy the colors you need for your costume, in this case, red, blue, and white.
With your glue gun, hot glue the foamies pattern ONTO your cereal box template (be sure to score your craft foam the way you would with your cardboard).
Construct the entire costume in the same manner (glue foamies to card then assemble).
Once it's done spray entire costume with a clear glossy spray.
This will drastically take the weight of the costume down and it will add comfort and squirming room for kids that don't hold still.
I used the above technique on a different project so I know it works, I just wish I could've used it for this costume since cutting cereal boxes is so much easier than cutting stubborn cardboard LOL.
Oh, by the way, the lights on the costume are reading lights from the Dollar Tree. The helmet was started from a camo/soldier helmet also from the dollar tree.
Thanks again for this crazy awesome instructable.
:)
Quick P.S. in Chemistry when we were looking at telephone poles, and discussing the functions of all the equipment, when Mr.Censored said,"Do any of you know what a transformer is?"
Before I could register what I was doing I raised my hand and said,"Robots in disguise."
Also, when it was Halloween, my school allows costumes, I saw someone dressed up as Bumblebee, and when she sat down for lunch, TRANSFORMED INTO A CAR!
lol, everyone would have laughed
days at school will be boring if noting like that happened:)

I've just started this as my "summer project," if you will. I take a lot of pride in having awesome Halloween costumes (this past Halloween, I did Two-Face to much respect), and I want to see if I'm up to the challenge of this masterpiece!
I just started with the chest piece, and I had to make it myself because I couldn't find a box in the right size. My edges are unsightly, and I'm looking for a way to cover them up. I was wondering if there were any tips about spackling cardboard edges. I've never done it before, and I don't want to mess anything up and have to start from scratch.
