Prusa i3 MK2: V2 holder clips for Y-axis' bearings (LM8UU and igus drylin RJ4JP-01-08) by MartinMajewski

Last crawled date: 3 years ago

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 more comfortable to adjust these clips for the ordinary LM8UU ball bearings, which come with the machine. As with Thing 1837936 (http://www.thingiverse.com/thing:1837936) you don't need the weak zip ties any longer. Instead, you can mount your bearings "pre-aligned" to the Y-carriage by using two M3 screws per bearing.
A further advantage is that the bearings are now aligned in the center of the Y-carriages notch. So there is no longer the risk of misaligning the bearings vertically. Nevertheless, the Y-carriage has still the 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 had 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 on 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
