IGUS update ?
Hi eveyone, I have been looking at the igus bushings for quite some time, and i remember that the RJ4JP-01 required to be pressfit to achieve tolerances. But I have had a look today and on the rj4jp-01, it now says "Secured by circlips, Plain bearing material: iglidur® J4" have they updated their bearings? if so that would be great for everyone. Theyre cheap and now apparently dont need to be pressfit 🙂

Common point of confusion with these, to the point that everyone thinks they require press fit. They have two versions of the bearings. I believe it's the yellow/pink ones that require press fit, while the gray ones do not (someone correct me if I am wrong on the colors). I use these: https://www.amazon.com/Pieces-Igus-RJ4JP-01-08-Printer-Bearing/dp/B076NWK2NK/ref=sr_1_1?ie=UTF8&qid=1522085530&sr=8-1&keywords=igus+prusa - If you look hard enough around these forums, you'll find the same information has been confirmed by someone who checked with an IGUS support rep. Also if you look at the bearing PDF guide they have, pretty much all that require press fit will have it listed, these particular ones do not.
Now that that is out of the way, do you want them? The answer to that is probably not. There's multiple reasons for this:
You would likely be better off with better quality LM8UUs.

If you do want to proceed, you can try my two modified parts:
https://www.thingiverse.com/thing:2835381
https://www.thingiverse.com/thing:2835392
One will reduce slack on the y-axis and the other will reduce slack on the x-axis. The rods can still move a bit more than non-Igus bearings but both parts eliminate one type of slack.
I hope that helps.

I can confirm the grey ones need a compression fit. However he was using 3D printed parts to do the compression, so it can be done easily.

Re: IGUS update ?
I re-designed some clamps i found on thingiverse.
Now i have some pretty well fitting clamps for my MK3 y axis.
I have a bit more torsion clearance than i expected, but everthing prints well since 70 hours.
I can post the stl´s here if you want to give it a try.
