This is a divider for the drawers of https://www.thingiverse.com/thing:2141153
The divider is thin enough that you can have 2 levels for each drawer. This is perfect for many small items like M3, M4, M5 nuts and screws etc.
there are various colors since this does not take much filament and I was using up my partial spools. Also, this will print very fast at 0.35 layers rather than the 0.20 layers. The layer detail is not needed for this project.
This may fit other eSun develped drawers.
