Flexible 1/4" Hex Bit Holder

This 1/4" hex bit holder is part of my EDC kit. I wanted something that could grip the hex bits but still release them easily, so I chose flexible TPU. The holder is designed to stretch slightly so it retains the bits, so it will not work to print this out of something rigid like PLA or PETG. I printed mine in NinjaFlex Fire Shore 85A TPU. I've been carrying one of these in my pocket every day for over a year, and it's held up well. I included a 6X, 8X, 10X, and 12X version in case you had a different number of bits you wanted to carry. Print solid in TPU. It's designed for 0.4 mm walls, which will give you one strong circle around each bit, and one continuous wave around the whole holder. I designed in inches, so you may need to scale by 2540% in your slicer.
