The white gear in the middle is the original broken gear. I modeled mine form that one. Identical.

The material is an ABS type plastic resin that is not so brittle as before. Just pay attention to my drawing

that comes with every one. It tells about not pressing it on again. That's why it broke to begin with.

Originally I made only the F-50 model, but a customer requested one for his F45. Exact same one.

These parts are like injection molded quality, this is not some toy 3d printer that uses the crummy spools.

Which is why I bought 3 printers so far.

Sold 9 so far for sales.
