Modular Watch Winder with 120V Motor

thingiverse

This is a modified version of this [Watch Winder](/thing:2666428) but uses a 120V AC motor. The original utilized a 240V motor with a drive shaft not found in the 120V version. This model moves the motor mount back to allow for the longer drive shaft, but also modifies the drive gear to accept the coupler. The 120V motor can be found on [Amazon](https://www.amazon.com/gp/product/B07F4CSM86). Make sure to order the model with the brass coupler, as the drive gear is meant to mount to that. It's a tight fit, so you may need to tap/press the coupler into the drive gear. As this model moves the motor mount back by 12.5mm, the winder can accept heavier watches without the longer legs. Only the mount and gear are modified from the original. You can use the same extension pieces to add additional winders just like the original. I suggest printing the watch clip with 100% infill as this will be bending/flexing during while holding a watch. I also uploaded a brace that can be used to hold together two mounts. I didn't want to use magnets that close to my mechanical watches, so this was a compromise. I ended up drilling holes in the bottom tabs on the mounts and using 4mm screws to hold the sections together. This makes the system pretty solid and with the brace, it's no problem to carry the motor and extension together. I'm working on a brace that will connect the motor mount to the extension mount as well. You may notice that I mounted a watch clip to the back of the extension winder. This works very well and clears the motor mount without issue. I am using a watch with a NATO strap, so it may come close with a thick metal bracelet.
