Prusa Mk3 Y Carriage With 4 Bearings

thingiverse

This is the dxf file for a design that I created based off the Prusa's 3 bearing Y carriage for the Mk3 printer and 24v Mk52 heatbed. This design allows for 4 bearings, 2 on each side. I am currently having this cut in aluminum and will upload pictures and performance information as I go. Edit 4 Dec 2018: I had this cut yesterday from .19" 6061 aluminum plate. Video of the cut can be found here: https://youtu.be/l_0kqAd1eqg Despite being almost 5mm, the carriage is very light (lighter than my steel one) and is very rigid. I found an error in the original drawing file where a hidden layer was generating some extra holes. That has been fixed. I'll post more as I get it installed. I have verified that all the holes line up perfectly with the Mk52 bed. Update: I got this installed and it is working perfectly. I used some block bearing mounts but you could also use the stock mounts.
