Printrbot M3 Screw Measurement Slots

After building many Printrbot Simple kits with educators, I drew up this jig to quickly sort the M3 screws for it. The slots represent the 6mm, 8mm, 10mm, 16mm, 20mm, and 22mm screws. Once they're sorted, we put them in labeled ice cube trays. Trust me, this saves a lot of time and headache during the building process.
