Hello,
A club at my school that I am leading is building a RepRapPro Mono Mendel, and we are sourcing the parts for the 3-color upgrade ourselves. I have been able to find everything except for the "double coil spring washers" mentioned on the RepRap
Wiki page.
The suppliers that I was able to find (Freeway Corporation and Shakeproof Group) are not interested in selling small quantities of parts, and all other online vendors that I was able to find do no stock the correct sizes. Does anyone know where I could find these parts in the required size (M3, or 1/8in)?
I also had the idea of simplifying things by substituting the washers for compression springs. There are a large variety of springs at
www.centuryspring.com, and after a brief search I was able to find one that seems to fit roughly the same envelope as the double coil spring washers:
Spring Specifications. Does this sound feasible?
