I designed a deck box to fit 100 sleeved standard cards and 2 20 sided dice. you will need magnets to join the top and bottom parts. This is designed to be supportless with some bridging required for the bottom and top of the deck cavity. If you want a cleaner finish you can add supports but it will take longer. The magnets you will need are 15mmx2mm magnet. They are the cylindrical kind. Please post a make if you make this! The inside space for cards is 100mmX70mmX70mm. Happy Printing.

Update: I tweaked the bottom deck cavity to print better when being bridged. I have also added a decorative file if you would like to resin print just to have a physical top that has no function except for decoration purposes.

Also I have included a stand. Its not the prettiest thing but definitely works to hold it which is nice because it was just sort of laying around before I had this.

Here are the magnets that should fit. amazon.com/VSKIZ-Different-Muti-use-Neodymium-Whiteboard/dp/B0BZYNZQKS/ref=sr_1_1_sspa?crid=OUWZE6DUFQIU&keywords=15mmx2mm+neodymium+magnets&qid=1692371129&s=industrial&sprefix=15mmx2mm,industrial,107&sr=1-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1
