Hi there, I am having problems with mounting a 3d printed HTD5m 15mm width pulley to my sk3 5055 motor shaft. Currently, I have a set screw going through the printed teeth into the drive shaft, which I have dremeled flat. I know 3D printing isn’t ideal for the motor pulley, but I don’t have the money to but them right now. I am printing with Nylon, as it’s the strongest I have. The problem I am running in to is after about 10 feet, the pulley starts slipping on the drive shaft. I used to have the problem of the pulley falling off the shaft, but I seem to have fixed that.
Anyone have any ideas? How did you solve this problem?
