Hi. I don’t own prusa machines so I can’t help you directly, but if you head to the prusa GitHub they have stl and scad files for their machines. Maybe you can print a similar piece if it’s common between the mk1 and 2 for instance.

I had the same happen to me! My knockoff bltouch got it’s probe snapped off in an unfortunate speghetti incident. I took it apart and replaced the plastic probe with a bamboo skewer that I cut and shaped to the dimensions of the probe. It’s been working flawlessly for 3 months now.

There are other versions with no pins required. But I found the pin ones hold up better in pla.

Is this loss?
