Y Carrage for Mendel Prusa
by foxdewayne, published
These are both 125MM high, so make sure you are set up to print that tall
Print out both files, install the bearings, slide them onto the 8MM rods and then glue the mounts to the small platform of your Pursa.
You can make them tighter or looser on the 8MM rods by tightning the 3MM scews holding the Bearing, if you want them looser than loosen the screws.
