Pulley for hacked sewing machine
thingiverse
This is a pulley designed for a Singer Starlet sewing machine. The design is based on the parametric pulley from droftarts (http://www.thingiverse.com/thing:16627). I used it after replacing the standard AC motor with a nema 17 stepper motor that just fit into the existing motor holder. The belt fits right on to the pulley and has the correct tension. The pulley is fastened to the shaft by two grub screws and nuts. Print Settings Printer: MiniCNCPrinterCutter Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.2 Infill: 15
