Here is a screwdriver bits holder for my electric screwdriver.
Fixed right above the battery with a zip tie.
Printed at 102.04% scale to compensate flexible filament retractation.
Printed at 230°, bed 90°, first layer 0.4 to compensate the elephant foot of the Flexifil.
Joined a little piece to test the scale, it must be a square of 15mm, mine was 14.7. But the must important is that you have to fit a crewdriver bit inside it to find your proper scale. It should be easy to insert and remove.
