Knurled Magnetic Hex Driver

Simple hex-key grip to make all those Allen Keys that come with 3D printer kits/etc a lot easier to use for long periods of time. Fits up to a 3mm key. Can hold it either lengthwise for use like a regular screwdriver, or cross-wise as a T-grip for torque.

Includes four little pockets for [these magnets](https://www.apexmagnets.com/3mm-x-1mm-disc-noedymium-rare-earth-magnet) or some other 3x1mm equivalent. For an easier installation on the two in the horizontal hole, pause the print at 14mm
