Ultimate Systainer Organizer Boxes - all sizes, easy to print

After being unsatisfied with all available Systainer³ organizer boxes I made my own. These combine all relevant features such as:

• easy to print - no supports, no post finishing, no overhangs
• all sizes, even half height (stackable)
• labels - each box has one or two slots for labels; either be fancy and dual-color print them (I recommend 0.25 nozzle) or just print a bunch of blank ones and use a permanent marker 
• tight - nothing falls out, even tiny stuff
• no wasted space - payload volume is maximized
• can be placed anywhere on the grid
• spool versions for cables / tubes / … - no magnets required for assembly, just 1 M3 bolt & nut

The boxes feature a seperate bottom piece that snaps into the container. This makes the boxes super easy to print and have the benefit of being replaceable with another version that creates two half-size compartments.

As (for some weird reason) the systainer boxes don't stick to the 50mm grid on the outer rows, other half-heigt boxes I found cannot be used there as they interfere with the edge wall. My version fits all positions though.

I printed mine from leftover PETG filament, which is the reason for the funky colors.
Some of the filament I used was rather old, so some printing defects are visible on the photos (I was too lazy to dry it out), so please don't mind those.

Please let me know if you want any additional size, I will add it as soon as I can.
