1/4 inch bit driver w/ recessed 4mm magnet hole

This is a 1/4'' bit driver for tight areas. I have made this pretty snug to hold the bit for awhile, but repetitive use will eventually widen the whole. I put a recessed hole in the handle where the back of the bit goes to allow a 4mm disc magnet to be super glued in place for long life use. I printed with a Dremel 3D40 at .1mm layer height and 100% infill. Hope you enjoy!
