I needed a bit holder for my drill when switching back and forth between Phillips and Robertson hex bits. Couldn't find a simple one that I could buy so I made one.
There is the external holder and 3 different size inserts, to compensate for minor variances between bit sizes and printer tolerances.
The 7.5mm is the one that works the best for me.
Included is the Freecad file that I designed the file in, feel free to make changes as needed to suit your needs. The insert radius is probably what most of you would need to adjust.
Note:
I printed the exterior holder in polycarbonate and the insert in TPU. Polycarbonate has high surface energy so double side tape sticks really well to it, I found PLA and PETG are ok but they tended to peel off sometimes. The TPU insert is "grippy" so it's a nice friction fit.
Printed at 0.16 layer height, 100% infill for the exterior holder and 50% infill for the TPU insert.
