Simple labels for the small bins in the harbor freight wall-mount parts storage bins https://www.harborfreight.com/30-bin-wall-mount-parts-rack-63151.html

Fit is a bit tight (takes a good press to get fully seated), but they are secure once in place.

Text is customizable in the .3mf file for whatever hardware/parts/label you need. STL file is only for the basic shape and does not include any text.
