I have made these boxes to serve as dividers in a drawer. I doubt they will fit exactly your drawer but here are some interesting ideas to take away:

• removable clip-on color rim, to change them with your mood
• the bottom is not completely flat, this allows for a much more reliable printing than flat bottoms which tend to adhere much less to the printing bed and which leave no margin for an imprecise filament flow. Before I added these grooves the prints would systematically fail after a few mm. With them I had a 100% printing success.
