Got your PM, just need to find the file again. Happy to share.Would you share the step or stl please?
Most of these seem to hold up at least as well as Zamak. Printed this with 100% solid PLA, have PLA-CF, Nylon, even Hi-temp CF infused Nylon if I need it. At some point, it is at least as strong as the source material, or stronger. I would rather replace this than wear the leadscrew more, so starting with a "good enough".BE REAL INTERESTING TO SEE HOW IT HOLDS UP AFTER A WHILE.
