Printrbot Simple Metal Manual Leveling Blocks

Due to auto leveling not being a good enough substitute for manual leveling, some Printrbot owners (including me) have switched to manual leveling.

After converting my printer I noticed that the belt was not perfectly straight and was pulling the bed down. These STLs fix this. Simply replace your stock Delrin blocks with these printed ones and pull the belt through the slots. I secured the belt with zip ties.
