An object for testing false crash detections on Y-axis

This is a simple model of cylinder that prints using 0.05mm layer height and Prusament PETG temperature settings. When printed in enclosure (I'm using Prusa Box aka Printer Box) at 125% speed, MK3S+ detects a lot of false crashes as discussed here

Adding a bunch of thermal imagery I took along the way. It appears steppers are doing fine, but Einsy is really hot (almost 60C) with the temperature in enclosure around 35-37 degrees. Throwing a fan on Einsy reduces the frequency of crashes from every 3 minutes to about every 9-10, but does not eliminate them.

Lubricating axes, loosening and re-tightening Y-Axis rails while hot, making sure the belts are tight, and putting shims on the Y-Axis roller seem to do the job though.
