Summary

I made this as an endstop directly for this dual fan satsana with Cr Touch: https://www.thingiverse.com/thing:7064753
the original endstop positioning hit on the bracket causing it to lose about 20mm of bed space and make the rollers jump at the end of the rail. this fixed that issue without having to update firmware offsets
i printed in pla and it works just fine
does require removing the x axis and replacing the front screw with 1x m412 screw in the back and then using 1x m48 screw through the front into the part itself. go slow and prescrew the screw into the part to cut the threads in before trying to assemble to avoid cracking
