Very simple box that fits cubes up to 59x59x59mm. Easily fits my MoYu AOSU WR-M as pictured. It will protect your cubes from dust and debris, and is a practical choice for when you bring your larger cubes to events and around in general.
• No supports needed
• No raft, no brim needed
• 2-part print (for best results, print in sequence rather than on the same time)
Consider using transparent filament for at least the lid; or the whole box if you feel like it. This way, you'll be able to tell what's inside at a quick glance.
Can be printed fairly fast (200-300 mm/s), EXCEPT if you use transparent filament, as the transparency will be much better at very slow speeds (30-40mm/s).
If you have cubes that are larger, such as 5x5x5, simply scale the box 5-10% larger.
Also consider taking this into TinkerCAD or another CAD program, to apply your own logo or name to the front and/or the lid.
