7 different versions of small parts bins for the famed Harbor Freight portable parts storage cases (#93928). These portable cases are the best you can buy for the money right now compared to the much more expensive Sortimo cases and generally hold up well. I posted similar bins for the Stanley 014725 cases which have a slightly different height: http://www.thingiverse.com/thing:579033 Harbor Freight does not sell extra bins which usually means you run out of the smaller ones quickly when storing electronic parts for instance. I also wanted bins with smaller compartments to store resistors/capacitors/etc. And of course you can print in different colors instead of being stuck with yellow. length (without lip): 53 mm width (without lip): 38 mm height (without feet): 47 mmPLA, .2mm layer, 10% infill (does not matter as the walls are thin). I recommend to print these upside down (except the ones with no compartments), i.e. with the opening on the bottom. The bottom of the bin needs some cleanup afterwards as it will print partially in the air. You can print them right upside up, but you will need supports due to the feet. The cleanup of the supports is somewhat difficult but possible with a sharp utility knife (put on some gloves or you'll cut yourself). I did experiment with detached feet (to be glued on afterwards), the results were not satisfactory so far. The feet never locate properly and/or the surfaces are not level enough to glue properly.
