You are advised to fully read the README as well as the wiki pages for better understanding on how to properly use the RS winder. **To download the entire set, please get it directly from the Github: [rs-winder.zip](https://github.com/vishnu350/rs-mainspring-winder/releases/latest/download/rs-winder.zip) (latest version)**, or choose your preferred version from the **[release section](https://github.com/vishnu350/rs-mainspring-winder/releases).** Due to the large number of files, only the 10.5mm winder is uploaded here on Thingiverse. This project helps watchmaking hobbyists build 3D printable mainspring winders for every possible size imaginable. Everything provided here is free and open source. This is the modern solution to hobbyist mainspring winding woes and it comes with **absolutely zero warranty**. You are advised to thouroughly go through this README, the [wiki pages](https://github.com/vishnu350/rs-mainspring-winder/wiki), and [video](https://youtu.be/EZvd_MKBOUQ) resources found here. Watch mainspring winding for hobbyists has always been a problem, as most of us cannot afford the $1500 Bergeon set to wind vintage unbranded mainsprings/barrels. Or sometimes the appropriate size just isn't available. This forces most casual hobbyists to resort to handwinding, which may kink or damage the mainspring. The RS mainspring winder was designed using FreeCAD+Python, and is easy to 3D print. It costs ~$10 to print a single set by most 3D print service providers. Alternatively, you may choose to just purchase a prebuilt kit from **eBay seller AndyShap2 [here](https://www.ebay.com/itm/125428348675) (single set)** or **[here](https://www.ebay.com/itm/125578735361) (complete set).** The RS mainspring winder works very well when properly constructed. **List of features:** - Guaranteed to work on all released sizes, since the generation process is scripted. - Cheap and easy to print with no post-processing/finishing or support material required. - Winds cleanly and safely, no more getting bits of skin stuck due to handwinding. - Can wind in both directions, clockwise and counter-clockwise. - Has knurling patterns on body for a good grip during use, along with clear size labelling. - PLA/PLA+ material is tough/elastic enough to withstand the winding stress. - Both PLA/PLA+ and staple pins are softer than steel, and thus it will not kink or damage the mainspring. - Never need to worry about wearing out the arbour hooks, as [staple pins are easy to replace](https://github.com/vishnu350/rs-mainspring-winder/wiki/Creating-the-Arbour-Hook-for-the-Winder-Base). - Pick any size from the generated [set of winders](https://github.com/vishnu350/rs-mainspring-winder/releases/latest/download/rs-winder.zip) (7mm-18.5mm) or [customize](https://github.com/vishnu350/rs-mainspring-winder/wiki/Customizing-&-Generating-the-RS-winder) it yourself. **Watch this YouTube video [here](https://youtu.be/EZvd_MKBOUQ) or [here](https://youtu.be/OAfQTk89P3s) (older) to better understand the RS winder parts and how it works.**<br/> **Discussion/Feedback: WRT forum thread [here](https://www.watchrepairtalk.com/topic/19340-3d-printed-rs-mainspring-winder-project-for-hobbyists/), or GitHub discussion section [here](https://github.com/vishnu350/rs-mainspring-winder/discussions).**<br/> If you like this and want to tip me: [Github sponsors link](https://github.com/sponsors/vishnu350?frequency=one-time) :)
