Description
This is a simple but strong lm8uu linear bearing holder for the y axis for 3d printers.
This part is printed standing up, so it is very (really very) difficult to break.
The internal diameter is slightly smaller than the bearing diameter, so it will remain quite tight. I recommend to print with ABS, which is elastic enough and will remain quite strong. Maybe PLA is not enough elastic.
It has very small clearance, so it fits the Prusa i3 frame (the version with bushings on the y axis).
Design is parametric. It can be easily changed to LM10uu or other linear bearings.

Instructions
This thing is designed using OOML ( iearobotics.com/oomlwiki ). If you want to print it just download and print the STL.
If you want to modify it install the OOML (instructions on the wiki) and compile using cmake or your favorite build tool

I take it you use Y-bearing holders because you don't have the ali frame with cut outs? Or is it that you didn't like directly using cable ties?
That's my case. I don't have the cut outs for the bearings, and in any case I feel it is more secured this way even if I had the gaps for them.
