I love using the harbor freight organizers for all my small parts but the latch needed work. The original ones started to get loose and wouldn't properly latch so I designed up a new one. This is also a great add-on to color-code your bins to locate what you need from afar. There is also a flat area to attach labels. No supports are needed since I designed the two support blocks. best orientation to be printed on its side, possibly using a brim since the contact area is smaller.
