This is a very simple and easy to print (no supports) additional bit holder for the Icon Mini Flex Head Ratchet set from Harbor Freight. This was designed to hold any standard sized bit, but I made this specifically for Magnetic Nut Setters also from Harbor Freight, so it fits the long length nut setters up to 0.69in outer diameter (half inch or 12mm typically). Printing 2 of these will give you a ton of extra storage and will fit the top or the bottom of the case.
Extremely easy to print, just lay flat on its face. Hole size is set to 0.28in inner diameter, so depending on your printer's accuracy I recommend reaming the hole with a long #2 Phillips as shown in the last photo. Works very fast so don't go full send.
