I made this Screwdriver Case cause I can't find any models that suits my liking.

This case can hold up to 30 bits (4mm) & a screwdriver of 17mm diameter.

The fitment may be a bit tight, I made this on purpose so that it won't slides out too easily.

You can try down scaling the Z-axis of the inner part sligthly (0.5~1%) if you want a smoother operation.

You can also:

-Print the outer case first.

-Then print the test piece to see if you like the fitment.
