Dual Watch Winder

thingiverse

This is a watch winder designed to hold 2 watches, ideal for metal strap watches as the removable arm allows for easy strapping on. A layer of felt has been added on top of the watch holder to prevent damage and ensure a secure grip. Assembly Instructions: 1. Print out all required parts, including 2 watch holders, 2 arms, 2 shaft-to-arm connectors, 2 motor shafts, 4 pin connectors, and 1 base piece each. 2. Additional components needed include 2 28BYJ-48 Stepper Motors, 2 ULN2003 Driver Boards, an Arduino Uno, 4 m4 bolts, and nuts. 3. Secure connector pins to the arm and watch holder using superglue. 4. Apply a small drop of super glue to the motor shaft coupler and attach it securely to the motors. 5. Insert 4 nuts into the holes on the bottom of Base1 and screw in the bolts, tightening the motor firmly in place. 6. Attach the shaft-to-arm connector to the motor shaft and secure with additional superglue. That's all there is to it! Post a comment if you require a circuit diagram for further assistance.
