Review on 🔧 Enhanced Performance with JISTL Plastic Single Double Reduction Gear by Chris Peck

The parts I received are similar to the picture but they appear to be left over from assembling DVD/CD players and cannot be used to mold gears without great effort. Good that the product is not expensive. The long rails in the illustration are from the DVD tray opening and closing mechanism. Gears do not have identical tooth and sprocket alignments. Printers do not use durable parts that can support more powerful stepper motors.
