SnapDeck Side Attachments

The Snap Deck is a modular playing card holder that I started developing to help my grandmother hold her cards on game night. It ended up growing into something much bigger with feedback from the community and a lot of time in CAD and printing test parts haha😄

------------------------------------------
This post includes all the side attachments currently developed.

Check out the main bodies here:
— SnapDeck Main Bodies

Check out the back modules here:
— SnapDeck Back Attachments

If you have printed out components prior to July 30, 2025, the side module mounting points have changed for strength reasons. Shoot me a message if you have compatibility issues, and I will figure out how to get you whatever models you need for your build!
------------------------------------------

Important!

If any objects are labeled with an "R", it's not because the piece wanted to become a pirate… it means you have to mirror the object (in your slicer) if you want to use it on the left side of the Snap Deck. The “R", or right side, is relative to looking at the holder from the front (card holding side), and it applies to the side attachments, back attachments, and body variations.

Also, I'm still developing the project here and there, so if you find certain issues that are not easily fixable, or if you have any fun ideas, let me know!

Some Things You May Need For The — Side — Attachments \_(ツ)_/

Depending on how well the tolerances of the press-fit nubbins turn out, you may want to secure down the attachments with an M3 screw (~6-10mm) through the convenient mounting holes all around the main body.

If you want to make the sand timer attachment, you will need a single M3 screw that acts as the axle and one of these timers that gets press-fit into the holder.

If you want to make the bell attachment, which is really more of a joke to make me feel like Hector Salamanca, you can find the one I modeled it around right here.

To make the score/life counter, you will need two longer M3 screws to secure together the assembly. Big thanks to this project for letting me take heavy inspiration in making my own counters.

Also, if you're making a joiner component to build a MEGA DECK, you should probably secure the two bodies together with the two M3 sized holes through the joiner.

Printing

I already designed in all the supports for you, so you should hopefully be able to just pop the models you want into your slicer, orient them, and send them off to get printed! Even the bores in the models are designed with a special bridge pattern to keep them from needing any support structure.

I mostly printed everything in PLA at 0.2mm layer height and default 15-20% infill, but different filament types and infill values should work just fine. As for the precision, you could probably print it with lower layer heights but it's obviously going to take a bit longer and not provide much visual/structural benefit.

Every printer is different!!! I did my best to tune the tolerances to apply well for most users, but you may need to do a little bit of sanding and/or use pliers to remove some of the supports if they are not too dialed in. Also, remember those M3 mounting points are there should you end up sanding too far…

Some More Info

If you want to watch some of the videos on the project, you can check them out on my YouTube channel right here.

Everything is obviously completely free 😉, but if you want to sell the SnapDeck yourself at a storefront or online, I will do my best to figure out some sort of commercial license situation.

Again, if you have any fun ideas or requests, you can always feel free to reach out or post a comment.

Happy printing and catch you later!
