Rod assembly jig for Rostock printed u-joint rod ends

This is a Rostock classic printed u-joint rod assembly jig that fits on 2040 extrusions, which allows you to set the length of your rods for epoxying. If you're using a Deltabob, Wolfstock or similar 2040-based deltabot, you can even leave this jig permanently assembled on the tower of your bot so that you can always make replacement rods of the exact length.
