KNRLR - a tool for making knurled bolts which are actually spiky
This nice thing attaches to your Dremel and lets you make your own M8 knurled bolts for your extruder. Technically speaking it's a "spiked" bolt, not a knurled one, but it's close enough. :) And yes, the name is supercheesy, but I like it anyway.
