Modular card deck draw

February 3, 2026

I’ve gotten back into 3D printing after I upgraded my decade-old Lulzbot to a Bambu Labs P2S. Man has the hobby changed! The new printer comes in handy for printing board game inserts to keep everything organized and speed up setup and breakdown on my table. Recently I designed a simple card deck draw after playing Wolfpack, which has six separate decks you pull for each round. Since I tend to sleeve my cards, keeping the stacks from falling over was a challenge during the game, and I figured if I could make something modular, they’d be useful for other card games as well.

Here is the STL. You can find the original Tinker Cad file here. The model allows for four 3x6mm magnets in the corners to allow for alignment of multiple decks. The slight angle at the base keeps typically tippy stacks of sleeved cards from falling over and creates an easy draw from the top.

I’ve learned a lot about physical UX affordance designing these simple prints. Along with the slanted base, there are finger slots at the bottom and sides which make it easy to grab the stack from the bottom when you need to breakdown your game and put it back in the box.

The model doesn’t require supports for printing and should work fine when using generic PLA with 20% infill.
