Are small PETG gears tough enough for setscrews to fasten to shaft?
I am just beginning with my Lulzbot Taz 5, using Gearotic (incredible program!) to produce smallish (1-4 in diameter) gears for quite low-load applications. I want to fasten the gears to metal shafts. Gearotic lets me produce a collar on the gears. For various reasons, I use PETG. I can drill the collar and thread it for a setscrew. But I wonder if anyone has experience in the long-term life of this arrangement. Is PETG strong enough that the setscrew won't eventually strip the thread so the gear comes loose? Thanks for any thoughts!
