TPU bitholders with capacities for 10 or 20 bits, and optionally,  one bit extender.    Designed for ¼" hexagonal screwdriver bits about 1" long.      Designed for a snug fit, expect the bits to stay in place hanging on a toolboard or in a backpack.   The bits can be forced out with a lot of jostling, but it takes some effort.     

 If you find the slots are not snug, consider reducing the size in your slicer by 1-2% in the X and Y directions.

Two sizes are offered, a 10 bit version and a 20 bit version.   For each, there is a version without a slot for a bit extension, and a version with the bit extension slot.

Recommend printing from TPU with a 95 hardness, and print with 5 or more walls and 25% infill.   

Each organizer has a hole in the end to receive a keyring.     I read reviews for several similar models on various websites,  there were always a few mentions that the keychain loop broke for a few users.    So these holders do not have a keychain, rather the keyring hole is part of the body of the organizers with sides 12-14 mm wide.   So putting in the keyring in place takes some effort, but it will be very hard for the keyring to be pulled out by “breaking” the TPU.

A finger spinner is included for a quick option to loosen or tighten many screws.   This should be printed from PETG or  a stronger material with 6 walls.    Not nearly as good as metal, but helpful to keep on the bitholder keyring for quick availability, and will work in many spots.
