Y Carrage for Mendel Prusa by foxdewayne Apr 17, 2011


History This is a derivative work of http://www.thingiverse.com/thing:4311 By http://www.thingiverse.com/jamesstaylor It uses 623 bearings with M3 washers on both sides of all bearings.

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.

Nice. Any chance of an SAE version?

Using bushings was the biggest problem I had with the prusa mendel succeeding but this fixes it! How about the same for the X axis? Maybe I'll have to make a Prusa now...


I loaded it last week.

Prusa open X carriage with bearings.

I found that a small extrusion the size of the inner diameter of a ball bearing around the bolt-hole make the bearings run even more smoothly due to less contact of the free-turning other side with the frame.

(hard to describe with just words)

You may look at my follow focus to see what I mean.

I know what your talking about. With the washers on each side, it moves very smoothly. Much better than the PLA bushings did.

Sweet! How long did it take to print the Y Mount? That seems like it would take forever...

As a side note, would it be as strong to separate the start and end part of it so it was two 20 or 30 mm long pieces? Just a thought. :)

Two and a half hours for one and two for the other. I printed them as one piece so that they would be in line with each other.
