My lid was hand-painted, and I only use a ender 3 pro, so no multi color prints.

Coping the original one

Materials Needed

• An Ultra Pro Mini Snap Card Holder
• 12x 6mm diameter x 3mm long magnets
• ~70m of filament (or ~220g PLA) for 3 walls, 30% infill

Build Tips

• I print these with 3 walls and 30% infill for extra strength. 
• Using different bottom surface patterns, like concentric or octagram spiral, can create unique looks. Use rectilinear for the top surface pattern for the smoothest surface.
• The magnets are toleranced for press fit. I recommend using an arbor press or a vice to press them in. The box needs two magnets per hole, and the lid gets one magnet per hole. (You can replace eight of the 6mm x 3mm magnets with four 6mm x 6mm magnets.) 
• Unsleeved cards may be scratched by 3D printed surfaces, depending on your print quality. Check for burrs before using, and consider only storing sleeved cards in these boxes. Be especially careful with glass- or carbon-fiber filaments.
