Step 4: Glue on little reinforcing strips

This seemed to add a lot of extra strength to the structure without being too time consuming or difficult.  Part of this I did while gluing the main pieces together.

Note the strips of cardboard in picture 2 and 3.  I folded these and glued them at the points of the open triangles where the windows and door were.

Next, I cut random strips of cardboard, folded them, and glued them over seams that seemed a little weak.  This seemed easiest if I glued on one side of the strip to one panel, held it until the glue set, then bent the strip back to apply glue to the other side and pressed it to the adjoining panel.  It can be tricky to try to hold a bent strip to two panels at an angle without one becoming unglued or something.  See pictures 7 and 8 in this strip for what I mean about gluing one side at a time.

I also glued a bottom to the door side to stabilize the structure.  I was too lazy to try to glue a bottom to the whole thing; I didn't have a huge single sheet of cardboard and it seemed like more work than it was worth.  You can see the bottom in picture 1 of this step.  Note the triangular corners from the bottom piece that I folded up and glued to the outside of the structure.  One side was a bit small so I glued another strip of cardboard over it to reinforce that one.
<p>Did this for my son with 2 extra disc shaped ears to make a Mickey mouse themed playhouse and painted the dome with blackboard spray so he could draw on it with chalk and the bottom part bright red. It was an instant hit but he already outgrew it.</p>
I don't have a hot glue gun. I wonder if duct tape on the outside and inside may work. Ideas?
<p>Yes it will. I used only duct tape on both inside and out. </p>
It might. Or you could save your change for a month and spend $3 on a cheap glue gun + $2 on a package of sticks. Walmart has some tiny but quite functional guns for around $3. I know, because I just picked up one after not being able to find my old one.
I have none moneys, but i suppose i could go sofa diving. we shall see. this project is on my to do list. :)
Duct Tape should work fine. Just be sure to apply it very carefully to guarantee maximum contact [no wrinkles if possible]. <br> <br>You could probably get by with Duct Tape just on the outside, but for maximum strength and rigidity it would be better to use it on both the outside and inside of each joint.
<p>Thank you!<br>We used duct tape instead of hot clue - worked out great.</p>
Made mine with no tabs and only duct tape, it turned out great! It is a bit too big, we will probably cut the height down 6&quot; or so. We left a triangle out in the back to let light in.<br><br>Here are my dimensions, it ends up being a 4'5&quot; diameter dome...<br>30 AAB<br>8 BBB<br>9 B x 32&quot; rectangles<br><br>A= 14.52&quot; 17/32 = .53125<br>B= 16.44&quot; 7/16 = .4375<br><br>I rounded up the B dimension to 16.5 and it worked fine. There are no extra cardboard supports, no floor, it stands great just with the triangles.<br><br>My son loves it, thanks for the inspiration!
Next time a bit bigger, but they loved it...
<p>That's what I did for my son. Thanks for the idea!</p>
<p>This is awesome, we are going to try to make one for our Vacation Bible School, since the theme is winter. Thank you for this idea!</p>
<p>Hi, I am a preschool teacher for 4 and 5 year olds. We made this and now have an igloo in our classroom. Thanks for the greatest project ever!</p>
<p>This definitely looks like something I'd have loved as a kid. It also reminds me of Thunderdome. 2 toys enter, 1 toy leaves!!</p>
<p>oh, excellent! I'll have to make one, then invite some kids round to use it!</p>
I'm impressed. Very impressed. Yours is the clearest way to plan and make a 'geodesic' dome. It doesn't seem very hard. <br> <br>Problem. I have been heaving every box; now I will have to save them. How will I ever make up my mind. (wink)
very nice idea and work....well done, now i feel inspired, thank you!!
Oooh, I could make one of these for the bunnies! I just won't have the amount of ink you put on, but I think they'd like it. Looks like plenty of room for at least 6 buns.
DRAT! I'm just sorry we binned that load of IKEA boxes last week!<br><br>Great instructable - and your dedication to decorating this just-so is remarkable. Lovely work.
Very cool! I like the steam punk colouring! (if thats what its men't to be!)
I saw a full sized version of this in Maker Faire Detroit 2011. It was about 10 or 12 feet tall and made out of plywood. Pretty spacious inside.
http://www.byexample.com/library/calculators/geodesic_dome_calculator/ <br> <br>Geodesic dome calculations made easy all ya gotta do is the labor you can makem kiddy sized or full sized like a house or garage this calculator takes out the heavy brain work !.
Maybe it's just me, but how should these numbers be read? In a 2V Dome it suggests I have &quot;35 Struts 30.9 cm each&quot; and &quot;30 Struts 27.33 cm each&quot;. These are the for the structure, right? So is the first number the A-lenght and B-length the second? Ugh, I'm having a hard time scaling this down.
The FAQ page on this site is awsome these guys covered everything to make it easier to understand check it out <br> <br>http://www.desertdomes.com/faq.html
I finally made it, but cat-sized :) <br>It inspired me to do a homage-'ible, http://www.instructables.com/id/Cat-sized-Cardboard-Dome/ , I hope you like it.
Wow! Is that even possible to make!?
COOL!!!! Im followin u
I'm impressed. Very well done, both craft-wise and as a mom. You have discovered what heaven really is like.
After reading this 'ible, I felt a need to create a playdome myself, you're never too old for these kind of things! I wonder how many boxes do I need to make one for two adults to fit in. :D (Oh, where would I even put it?)<br><br>And our new cat happens to love cardboard boxes, I could make one for her too so she would spend more time out from under the sofa.<br><br>One idea would be to try and make this out of fabric-covered parts with velcro to attach it together (and make it easily collapsible), but would it hold its structure? Any ideas, anyone?
Mod Podge - several coats should do it. I think they have one that makes fabric really hard. I'm guessing on this, but I've seen plans to make fabric boxes, and they use stuff like this. Google 'fabric boxes'.
Maybe if u could make triangle frames out thin plywood or fiber board or something light and cover the surfaces with cloth.<br><br>I think the main point of constructing a big structure is to make it light to prevent collapsing and attach the parts firmly to each other.
I was wondering how tall this turned out to be with your dimensions.
What a gorgeous pair u got there, and the idea of the dome is amazing, children always find interesting and stimulative tiny places, congrats!
Bucky, would be proud of this, its the kind of thing that he advocated.. This is what the octahedron is good for it divides evenly at the hemispheres..this is a three frequency, about thirty years ago I built this exact configuration ( not out of cardboard ) and lived in it for around 4 years, my mother moved into it after I moved out and still lives in it today.. Her highest utility bill has been under 80 dollars.. it was insulated on the outside of the shell with two inches of double foil faced urethane foam.. I like living in it better than any structure I have lived in..It was small about 900 square feet with the balcony bedroom. I plan to build one more to live in before I pass from the world.. It will be built much like this one only out of foot thick foam and shotcrete ... <br>Isn't wonderful how good ideas just live forever.. :) Thanks to Bucky fuller and you, your children will always see space as something different...
JWPatt,<br><br>would you make a 'screen' to ''hold'' the shotcrete? sounds like your HOUSE had an even temp all year round,<br><br>do you have pic's of your house??
I would definitely use either multiple layers of poultry wire or metal lath which ever turned out to look the easiest to work with based against the cost ... The R factor of the dome was an R 16 but gained a great deal of radiant heat retained and reflected because of the double foil facing.. The one I have planned will be in the range of an R 48 optimum and realistically more like an R 40 .. We have built several tube frame domes.. and have a 9/10s tube dome mounted outside my business on concrete piers.. Its a 16' diameter.. dome. <br><br>I have pictures of the one I lived in somewhere just have to find them or go take some more..
Thanks JW,<br><br>gezz, R48 is hugh, no wonder the HVAC was so low, <br><br>may I suggest you look at a product called ''hemp-crete' .com, amazing stuff<br><br>can't wait to see the pictures
forgot to ask,, where your 'R' values in the double digits??
About 25 years ago, I saw directions for constructing a cardboard geodesic dome in Sunset Magazine. I decided it would be a good project for my 4th and 5th grade special education students. They had to measure and draw the triangles; I did the cutting. Like you, I added 1&quot; flaps around the triangles. We didn't use any squares. Then the students assembled the cardboard triangles with 1/2&quot; #8 machine screws, washers, and nuts. Because this was a reward activity, after they finished their assignments, it took a couple of months to complete. They eagerly did their English and math assignments so they could work on the dome. The finished dome was approximately 4 feet high and 6 feet in diameter. We didn't paint ours, or put windows in it, but we left one triangle at the base open for a door. All the children (all boys) could fit inside. They took flashlights inside and used it for a reading corner the rest of the year. At the end of the year, the fire marshal ordered it taken down, but by then it has served its purpose.
consider scaling to a gingerbread house size,
This is GREAT i am making one as I speak....Only this one is for my dog...Thanks a MILLION for the time you spent making yours and for all the time you took to write and share this recipe, that is so creative and detailed....Thank You....
I haven't seen any of your other ibles, but if they're as creative and complete as this one, put 'em together and WRITE A BOOK! Very creative and your kids seem to be totally enchanted with it. Good job.
This is AWESOME! Lucky kids for sure to have a mom that's so creative!!!!!<br>
bloomin' marvellous! <br> <br>thanks for sharing and major kudos to you.
This is awesome! I wish I'd had a sweet playhouse like this when I still fit inside of one. Also, my favorite line in the whole thing, "I found a suitable one that people suggested homeless people use as emergency shelter." Brilliant.
if you scale up your triangles, you can make it to fit you at any age. You deserve a play house, you have my permission to build one. Hugs to you.
Oh! That reminds me... here's the site that had the instructions which inspired this instructable. It was linked to by some other site (which was the one that suggested its use for homeless)<br> <br> <a href="http://www.fetchaphrase.com/dome/">http://www.fetchaphrase.com/dome/</a><br>
Aww cute pictures :3
looks great! A LABOR OF LOVE TO BE SURE!!!!!!
Really excellent quality cardboard can be found at upper-end fine furniture retailers, mind large screen plasma-LED TV boxes are great for such purposes too but the harder to find honeycombed shipping boxes will offer your projects longer playlife and a much stronger construction.
How big is this thing? I would love to make one for myself as a reading area.
