I noticed an issue with my RRP Tricolor Mendel's vertical X carriage, in that the lower LM8UU linear bearing would get dislodged from under the carriage, causing the heads to shift while printing.

I took the original X-carriage STL file, and modified it in Sketchup to include two slots above the lower bearing flange to insert zip-ties through to secure the bearing.

I haven't printed this yet, but I am going to try with a 0.3mm nozzle and a 0.1 layer height tonight and see...

Temporary fix is to put a pair of zip-ties around the outer edges of the LM8UU bearing, and secure the zip tie with a few small drops of super glue so it doesn't slip off.
