a short 2-slot bit holder implement, able to hold three 4mm bits. It is specifically designed for the Mini Flex Companion; it will likely fit in other short slots, tho I've not tested yet. EDIT: Tested, It will fit in the Flex Companion and Flex Mini Companion, but will not fit in the Flex Modular Pliers, unfortunately. I am exploring possible redesigns to fix this,.
I used PC-blend, and recommend it if available. Other filaments can probably be made to work, but this definitely benefits from rigidity, strength, and dimensional accuracy.
Print at 100% infil, with maybe 4 perimeter. The holes are designed for either 1/8" or 3mm diameter magnets,- if you use 3mm, you might want to use glue. Cheap generic magnets will work, but I recommend getting good magnets if you want the bits 100% secure. For expensive good magnets, I got these, 1/8" by 1/32" grade N52 magnets. For most people, these grade N50 magnets are a lot cheaper and will be good enough. (The magnet holes are 2.55mm and 5.25mm deep)
This design went through a surprising amount of tweaks to get it working well, I hope people get use out of it! This implement cannot lock upright (had to make room for the magnets).
