This was based on the original prusa parts to mount the endstop on the smooth rods. I recreated the design based on that and removed the platform to mount the endstop. The idea here is to replace the black steel ring in the picture because the steel ring can't fit on the other 3 of my rods due to slight size differences. This rod clamp replaces that and also for those people having the same x-axis design as mine (refer to the picture). One of the smooth rod slid out a little bit when I tried to print something with 50mm/s because there are no rod clamp to stop the smooth rod from being slid out due to the fast carriage movement This uses m3 bolt and nutsPrint this with full infill to give best rigidity I printed mine using someone's printer, zortrax z-abs and should be okay for you guys using conventional abs too
