This was an idea brought to me by my childhood friend who was looking for a way to carry normal 1/4" bits in his Leatherman pouch to be used with his ratchet kit. As you can see in the second picture, the bit holder on the right from Leatherman houses proprietary bits that are double sided and thinly made. This holder is the same size but can hold normal bits allowing for a wider selection if Leatherman doesn't make a version of the bit you typically interact with
This holder can fit 10 bits (prototype with 9 bit slots used in pics 1, 2, and 4) and utilizes a magnet to secure them inside the sleeve. It is 3D printed with PETG and fits right in the Leatherman carrying case.
