Tom's simple modular table organizer V2

I like simple things. If I can choose, I prefer modular things which can be extended later and 3D models which are easy to print without supports and all day long waiting. These 40×40×40mm containers are simple and with thin casing – only 0.8mm for two walls with standard 0.4 nozzle. And the holders can be used with hollow containers or these with inner 2×2 grid for storing thinner things.

Tip: Use this hollow boxes for the tests of bed adhesion with new materials. If everything works well during the first several layers, leave them to print. So after some time you will have several boxes which you can use on the office table (with holders or without them).

EDIT 160209: Added two more divided boxes.

Note: Use standard 0.4mm nozzle.
