Summary

Designed my own mounts because I had some confusion on other versions: would the screw-type ones work on this device? Which block worked from the other version?

I noticed that my two linear rails were different heights and was planning to shim one, but the base plate varied by more than this amount, so I decided to use the height of these supports to achieve a level bed. The goal was to ensure the plate could support 3d printing (which I've never tried on this machine). When I started, there was a 0.51mm variance on the XY axis, which would have likely precluded proper first layer adhesion. Through the use of assorted spacers, I was able to reduce this to 0.04mm which should support proper print adhesion with only minor first layer squish.

I recommend printing four of the 2.0 lowers, then assessing if you need taller or shorter ones. My printer used 1.9, 2.2, 2.2, 2.5 so who the heck knows what you need? (put it in the comments if you use this)

My SBR16 rails, at the time of this publication, have duck brand double sided tape on the bottom, and are not even taped down (the blue backing is still in place). Theoretically the rails could move if a bearing binds. I'm probably going to stick them down at some point.

Note that the upper block needs to be mirrored. sScreenshots shown are Prusaslicer. I've never used Luban for 3d printing so can't help with analogous commands.
