Copic Holder with Stand

Edit V2: Added some extra wall thickness to get a better print quality.

I am studying Productdesign and this was a quick exercise. I have exactly 24 copics and needed a holder for my desk - let me know if you like the design and need a bigger one. 

Depending on the printer, infill and the material you may want to use more than two perimeter walls. Otherwise there might be artifacts on the outside from the inner structure. 

Stand can be printed flat without supports. Core can be printed upright without supports.
