Prusa i3 frame connector
Description
No more trouble with the washers when attaching the y-axis carriage to the Prusa3 frame.
Instructions
Put them in between the washers on the long y-axis threaded rods. It will help you attaching and tightening the frame while keeping each washer on its side. This part is designed for 6mm thick frame. Mine is acrylic but it will work equally well on an aluminium frame.

It is for the Prusa iteration 3 by Josef Prusa. Same guy but radically different design from Prusa Mendel.
