I liked the https://www.printables.com/@Satellietje model, but I needed to keep more bits with the screwdriver, so I created similar stand in that way.
The screwdriver has bits with diameter of 8mm hexagon (standard is something like 6.4mm).
I will be publishing the bits reduction once I finalise its dimensional tuning.
No supports necessary
I used PETG, but I guess any material should be fine.
Enjoy
