Summary

Spring loaded belt tensioner for Prusa Mendel.

Instructions

Print two of each part.

The parts were made in SolidWorks so unfortunately I don't have any OpenScad files for them.

All STLs have been loaded into Netfabb and repaired to ensure they are perfectly manifold.

The vitamins you'll need for assembly are a 608zz bearing two extension springs and either an m3x20 screw or a 4-40 0.75" screw. Rather than describing assembly it is probably easiest to just look at the picture. Insert the screw through the base of one of the bearing holder arms and screw them together.
