And I dont see how much you would have too pull for it to get worm enough to melt.
But I am waiting for a special more expensive material, designed for printing gears, so with that thing, it should be unbreakable. i will have to make few test videos asap.

Hmm, printing gears
no tanks unless they're printed on the highest quality professional printer in sintered metal . How are you keeping a tight bearing bore in that printed resolution ? How is it for longevity . IMHO, home printed parts are good for cosmetics , but are prone to failure doo to the porosity in the microscopic structure . Parts machined,injection molded and cast have a consistent grain structure which is paramount in the parts strength . Yes, it looks "strong" with all the bulk around the bearing journals, but is it ? A good well placed single weld bead is in most cases stronger then multiple layered poor weld beads .
In short , I applaud your effort for one self . I would consider a different approach of manufacturing if you plan to sell .
