Mini Bit Driver (1/4 drive)

Mini 1/4 drive bit driver. Has slot for a 3/8 X 3/8 X 1/8 inch earth magnet. I added the STEP file so people could change the initials on the bottom. Also I added an STL file that says Blank at the end with no initials if someone just wants to print one. I used 3 perimeters and grid infill. Don't think it matters.
