Summary

Remix of the very cool "Finger Hex Wrench" by RonaldWalters at https://www.thingiverse.com/thing:3985566

I wanted to challenge myself and do a complete from-the-ground up redesign (reimplementation?) of the original finger wrench in OpenSCAD.

Here are some changes and improvements I made:

Still has 1/4-inch hex version
Addition of a 4mm hex version for compatibility with iFixit style mini-bits
Changed the magnet to a larger 10mm diameter by 1.8mm thick rare-earth magnet. This magnet is able to hold the finger wrench to a magnetic surface (even upside-down!) and also holds the bit in the wrench.
The magnet now mounts on the underside. I recommend using supports for the magnet cavity.
Removal of all fillets and replaced with chamfers, which makes the underside print cleanly with no support (apart from inside the magnet cavity).
Full source code included (SCAD and SVG)
4mm hex-bore is oversized by 0.46mm to compensate for well known issue with 3d printers undersizing holes
10mm magnet hole size is oversized by 0.4mm
