ATTENTION: Please read the project's update notes at the bottom of this page!
I add to my effort to make the linear system of the Prusa i3 MK2 more stable, reliable and easier to adjust these clips for the ordinary LM8UU ball bearings, that come with the machine. As with Thing 1837936 (http://www.thingiverse.com/thing:1837936) you don't need the flimsy zip ties any longer. Instead you can mount your bearings "pre aligned" to the Y-carriage by using two M3 screw per bearing.
A further advantage is, that die bearings are now aligned in the center of the Y-carriage's notch. So there is no longer the risk of misaligning the bearings vertically. Nevertheless the Y-carriage has still full range of operation, because the clips for the side of the carriage with the two bearings, are designed to slide into the gab of the frames corner pieces.
There are still two things to consider:
-
Though I have the LM8UU bearings and tested the fit of the clips on them, I have not tested them mounted directly on my machine. The reason is, that both of my machines are equipped with the igus RJZM-01-8 bushings and in heavy use.
So I ask the Thingiverse community to give me feedback of how the clips perform and what I should improve. - According to nillabean (YouTube Video: VYW1p3T9tKo) the drylin igus RJ4JP-01-08 are very good, stiff and yet affordable linear bearings (not to confuse with the omnipresent RJMP versions). I have tested it myself and also got positive feedback from the community. They fit and therefore the RJ4JP-01-08 are now "officially supported" by these clips! :-D
Thank you!
Please also take a look at my other designs, printer parts and tools.

Sending a tip over Thingiverse will buy me some coffee to stay productive. :-)
Thank you very much.
