I created this part for the holder for my Klein Tools screwdriver. (https://www.kleintools.com/catalog/multi-bit-screwdrivers/27-1-multi-bit-precision-screwdriver-apple-bits)
The part has two "poles" that should not let the tool fall out. I use Gorilla double-sided tape to mount. It worked well.
Feel free to download :)
