FingerTech S3M Timing Pulley - 9T

FingerTech timing belts and pulleys work really well together. I used their handy web calculator to position the gears to minimize belt slack which worked perfectly for me. Overall very happy. My only regret is that I didn't know about FingerTech on my earlier projects, they would have been so much easier (and might have even worked). Make sure you have an allen wrench to fit the small set screw.
