Finger Hex Wrench - 4mm and 1/4-inch
thingiverse
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
