Small Screwdriver Bit Organizer

An organizer for small precision screwdriver bits (e.g. iFixit). I designed it to fit to my Proxxon/Dremel Bit Organizer.

Model Details

• The organizer can fit 66 tool bits
• Dimensions (length x width x height): 101mm x 107mm x 72mm (3.98in x 4.21in x 2.83in)
• The holes are 5mm (0.19in) in diameter. Normally 4.5mm are enough, but I added some margin, to avoid any requirement of postprocessing the holes.
• The holes are 16mm (0.63in) deep
• the holes are shifted between the individual layers to make access easier.
• The lower tray is 25mm (0.98in) deep.

Tips for printing

I originally had the lower half of the model hollow, but changed it after I sliced it and didn't found much improvement in print time compared to a version with low infill. As this model doesn't have high structural requirements, I made some changes to my default print profile.

• Reduce to 3 bottom layers (It is only a flat surface)
• Reduce to 5 Top layers (Adjust this in combination with temperature and infill. If you print hot and with less infill, you might need more to get a flat top, otherwise even 4 can work)
• 10% infill
• Reduce to 2 Outer walls (if you don't mind ghosting)
• A 0.6mm nozzle doesn't hurt the quality at all.
