Thumb screw for M3 socket head

This is an easy-to-print thumb screw attachment for a M3 socket head screw. It increases the grip area and makes it easier to turn. Also converts things into fidget toys.

It's designed to be a bit tight when it goes on the screw.

Printing instructions

• Print the .stl file as-oriented (driver opening up).

Notes

• My entire design is parameterized in OpenSCAD. If you'd like any modification (e.g., screw size, grip, outer size, etc.) please reach out and I'll see what I can do.
