Winderoo is open source firmware, which adds the following:
- 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.

Some general printing advice:
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 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.Most importantly, have fun!
