3MM thumb screw for prusa I3 bed height adjustment

I could not find a thumbscrew that worked for the hotbed my Prusa I3 on any site, all of them were too wide or too tall to clear the frame, so I made one.
Just press a 3mm Nyloc nut into the bottom of the thumbscrew. A dab of two part epoxy may be needed to hold it in place (depending on your printers calibration). Enjoy!
