WARNING: Needs to be printed in flexible material, otherwise you cannot get the bits in or out!
My case for the hex drill bit set Bosch 2 607 002 826 broke, so I made a new one from flexible material (TPU 95A).
To take out a bit, you bend the upper part backwards, so don't try to print in PLA!
No supports were needed. Extrusion factor was 1.10, as is common with TPU.
The author marked this model as their own original creation.
