Prusa X-End motor and idler with lm8uu bearings holder
by DXBLouie, published
Description
this should provide enough space to fit two lm8uu bearings with a bit of a gap in between.
this is my first time using openSCAD, so i can only hope this works and helps someone!
Note: the STL files were compiled for a Metric prusa

Does someone know the distance between the threaded and smooth rod, from centre to centre ??
Thanks for your help :-)
Perfect fit. This thing has repaired my X backlash, THANK YOU!
very good, bearing goes in no problems I pressed it in using a G clamp, solid as. :)

mine took a TON of sanding to get the bearing in. I'm not 100% sure it is the design, but that seems to be a recurring theme. next time I print one I may loosen up the tolerances on the bearing holder a bit.
I find that adding a cone to the top and bottom of the bearing cutouts helps you insert the bearings...
Otherwise these work great.
The channel for the LM8UUs came out a bit too tight on the one I just printed. I can *almost* get them in
…
There's also this one http://www.thingiverse.com/thi... though it uses longer LM8L bearings (45mm long), but could just be fitted with 2 x LM8UU. Though no openSCAD file, only STL.
I think what people end up doing is printing a little snap in holder and gluing that into the default channel. That's what I did anyhow.
Me too but probably because Anthong helped me build mine... :-P
