Honestly, I believe the people that are experiencing idler breakage might be using lower quality PLA… which is very susceptible to less-ductile characteristics. I still recommend ABS (engineering grade) when used as a part of a mechanical system. This design has exposure to both heat and high pressures which PLA (commodity) was not designed for.

This is a great design and I do not believe the v2 idler was necessary. v2 idler just adds more parts …which allows more things to go wrong. Get over the fear of printing with ABS… It is a great material once the “Cons” are overcome. It took me 8+ weeks to figure it out.

I will be releasing my own revision of you design soon 

Addy rant end.
