Universal Pen Blank Drill Vise Jaws

thingiverse

This a simple pen blank jig that allows you to print universal jaws for pretty much any vise. There are holes which accommodate the rare earth magnets found at Harbor Freight (https://www.harborfreight.com/10-piece-rare-earth-magnets-67488.html). Simply print 2 of these and push fit, or glue in the magnets. Simple. Easy. Done.
