The Open Source Watch Winder (OSWW) is an open source high quality, modular, watch winder. For $40*, you can build yourself a 3 watch, watch winder, with user-replaceable parts.

• Modular! Build one powered unit and daisy chain unpowered units together.
• Open Source - pull requests welcome
• Minimal electronics / programming experience required
• Easy to print

Winderoo is open source firmware, which adds the following:

Supercharge your build with Winderoo!

• Settable RPD (rotations per day) between 100 - 960rpd
• Single direction (clockwise / anti-clockwise) or bi-directional winding.
• Settable start time. Have it wind while you're asleep, or while you're away, or anytime for that matter!
• Manual cycle start / stop.
• 3 seconds of rest after 3 minutes of rotation, in every mode.
• Estimated cycle duration (how long it'll take to wind your watch).
• Cycle progress display (how far along the current winding routine is).
• Software or optional physical button to trigger ON/OFF state, so you can disable the winder completely.
• Simple setup. Flash the firmware and File System with a few clicks, then connect your phone (or other device) to the winder's setup wifi network & add it to your home network.
• There's no app required! You control it from a web browser.
• Minimal electronics / programming experience required

Note: Winderoo has a separate set of hardware requirements to the OSWW and has much more complex firmware flashing requirements. If in doubt, stick with the base firmware provided in the OSWW repository.

• March 2023 - RELEASE on Printables (https://www.printables.com/model/421249-osww-the-open-source-watch-winder)
• March 2023 - Add source files
• April 2023 - Add Winderoo

The following models will require support:

• STRUCT_mid_plate
• watch_mount

The model is designed to be printed with PLA, therefore tolerances are spec'd for that

• Tolerances are between 0.1 - 0.2mm

3. Print with 25% infill

• This will the increase overall rigidity of the model, especially when dealing with the motor's torque.
• This will also give you a "premium feeling" product.

If your printer has a tendency elephant foot, you'll need to file down some of the pieces.

• For example, the mounting_dowel's outer lip will need to be filed down so the mounting_dowel_sleeve can easily slip over it.
