About: Hobby programmer, woodworker, Arduino enthusiast! I love tinkering, puzzling, understanding how everything works, and fixing anything and everything!

"Baby, stop stealing the remote!"

Hmm... doesn't work.

Our 18 month old always picks the smallest remote (Amazon Fire TV Stick) from the bin and carries it around. Then she proceeds to lose it in the most random place in the house that will take us a day and a half to find!

Ah! Anyone else have this problem? If only we had a decoy remote! Something that looked and felt like the real thing?

Let's get started!

Note: If you are brand new to 3D printing/modeling/design like me (less than a month now), or maybe never touched a 3D printer before, these instructions show the basic steps needed to complete a 3D product. I hope this helps! In reality this project turned out way better than I thought it would!!!

Step 1: Discovering the Real Deal

How in the world are we going to replicate this perfectly manufactured remote by Amazon? Where do we even start?

First thing to replicating an object with a 3D print is discovering everything we can about it. We use good digital calipers (or a ruler) to take measurements as best we can of all the major parts of the object. For something like a TV remote we sketch it out on paper, noting the basic shapes, measuring the dimensions, buttons, and distances between each component.

Once we've gathered the info on it, next step is reproducing the sketch in a 3D model.

Note: Besides PLA filament, the first thing I bought to go with my printer was a good set of digital calipers. Here is a link to the ones I bought from Amazon: Vinca Calipers

Step 2: Modeling the Counterfeit

Wait wait wait! We have to use 3D modeling software? Yikes!!!

I know this sounds like a daunting task, but try it! It was much easier to learn than I thought. I had used Tinkercad just a little for one previous project, and fumbled through that one on my own. This time, I enrolled in the easy 3D printing class offered by Instructables (Easy-3D-Printing Class) and in one evening learned the simple skills and tricks I needed to design a TV remote. I honestly am still surprised how easy and fun Tinkercad is to use.

First, we use common shapes to simply piece together the remote. Cylinders for buttons, boxes with a radius on the edges for the top and bottom of the remote, etc. The video shows how quickly we can model a simple remote from measurements in just 7 minutes! (Ok, ok, so it took me much longer than 7 minutes the first time I did it.)

Here is a link to the first version product created in the video: Fire TV Stick Remote v1

And a link to the second version where sloping sides were added: Fire TV Stick Remote v2

Step 3: 3D Printing the Prototype

With Tinkercad it is super easy for us to export the design to an .STL file for 3D printing. Then we can just use free slicer software such as Ultimaker's Cura or Slic3r to prepare for printing. The slicer software takes the 3D model and establishes the settings for 3D printing. After printing the prototype, we measure and compare the fake to the real deal to make sure everything lines up. If adjustments are needed or anything looks off, we go back to the modeling step!

Step 4: Refining and Final Printing

After printing the prototype, the details and proportions were an exact match, but something still didn't seem quite right to me? Just one thing was missing... weight!!! I realized even with a great paint job, filament is very light and my baby will not be fooled. I needed to make it EVEN MORE REAL!!!

So, if a real remote weighs about as much as the batteries inside, why don't we just use 2 dead AAA batteries to make it about the same weight? Great idea! (Thanks!) So we measure the battery dimensions, add them to our sketch, and then add a hollow space inside the print to hold them side by side as shown in the video. We include a small inset cover to glue on the back to hold the batteries in as shown in the video. Last of all if we are adventurous, we add the little etched logo at the bottom!

Here is a link to the final version adding battery slot and logo: Fire TV Stick Remote v3

Step 5: Assembling, Sanding and Spray Painting

We next clean up the print by removing any strings and cutting off the brim and/or supports as needed. Then we just pop 2 dead AAA batteries into the slot with some folded paper to make it snug, and superglue the cover on.

Since I'm still honing my printer, I printed with a brim and didn't print with really fine detail, so I decided to try some sanding. It took some added time and wasn't very easy to hold while sanding, but there is a great tutorial here if you want to make it much better!

For basic sanding, we can use 200 grit sandpaper first, then wet sand with 400 grit sandpaper. It takes about 10-15 minutes to see it become more smooth.

After wiping off the dust we spray paint with our base color, in this case black satin, using multiple coats all around on both sides.

Step 6: Finishing the Details

At this point we're just missing a few important details! Using a toothpick, we dip the tip in our basic white paint, making sure to not get too much on the tip and carefully draw the button icons. Too much paint on the toothpick tip means we won't be able to do the fine lines. We take it slow and re-dip a lot, wiping off any excess if we get too much.

Step 7: Planting the Decoy

Now we just put the original remote on a shelf the baby can't reach and plant the decoy along with the other remotes. It works!!! See if your kids take the bait as well...

    Pretty much all of the upgrades are listed on Thingiverse. I think this link should work to a collection of things I've printed or planned to print:
    - https://www.thingiverse.com/JonathonT/collections/ender-3-mods

    Also, here are two links to Reddit pages that are more new user guides for the Ender 3. Most I found listed there or in youtube videos.

    There is also a facebook group, but it isn't easy to sift through to find what you are looking for: https://www.facebook.com/groups/Ender3dp/

    Good luck!

    Instead of free-hand paint the white symbols, could you have used the printing program to create an embossed space? Then, just fill in the depressions with paint and sand off any excess above the short "rim". It would be neat, and easy (with the design and printer doing the fine work). But, I do not know the program, so I do not know if it is easy to add specific "negative space".

    Yes, certainly doable! I did something similar with the Amazon logo. Will have to try something like that

    My 20 months old steals my motorcycle keys.. and there is no way I could fool her with cheap printed materials to impersonate metal keys, not twice.. I see you did manage to trick your wife in letting you buy a 3D printer, this is something I should try with more chances of success :)

    Remote control is the first thing that kids break when they start to even crawl! Mine still manage to drop it even now they are much older....not to mention fighting over the thing! Wish I had one a few years ago but may be worth making on even now ☺ thanks for sharing. Useful Tinkercad lesson too!

    Thanks! And I agree on Tinkercad. I found just watching someone else use the program helped me learn so much quicker what it is capable of. That’s why I included those. Hope it helps for those new to it!

    i have this issue with my 18 month old. but i think it has more to do with "this is dad's remote" than it being a toy. when we're watching tv together, he'll fake wanting something so i get up and he moves to my spot and takes my remotes and pushes buttons like he sees me do.

    I just wonder how much time you spent in total on the project. It seems like a lot of work; although the result is really nice. In the end, you still have to go and look for the decoy in order to fool your kid time after time again. ;-)

    :) Haha, there was some time involved (mostly in the modeling and sanding) but since I was learning how to 3D model and print while doing it, it was mostly to learn and just see if I could do it! If I started from scratch now on another similar object it would probably take less than an hour to prep and start printing a prototype, then an hour to sand and paint after it is printed. Printing an object like this does take multiple hours too. So it could be done in a day if you only have to print once. Cheers!

    Nice idea, but I find it cheaper to buy those Chinese clone remotes for a few bucks each than buying a 3D printing machine and making them. Or make all your remote unreachable by placing then on high shelves, then make all adult users remember to return the remotes to the shelves after using them.

    Haha, thanks. If only... I have older kids that also use the remotes and therein lies the problem. :)

    Of course a real remote costs about $8-$10. What I would be interested in is being able to print a battery cover for any remote out there.

    Wonderful job and great instructable. You got my vote.
    I have one concern... dead batteries leak. I would suggest picking up some large steel nuts at the local hardware store to provide your internal weight.

    This is so funny, and I'm glad you showed a picture of her not giving the fake remote back. VICTORY! Also, I enjoyed that you showed all your iterations and making it better and better each time.
