OSW Magnetic Paddle Shifter

3D Printed Magnetic Paddle Shifter

These 3D printed magnetic paddle shifters are designed for sim racing with an OSW direct drive wheel.
The shifters should be compatible with other wheels as well but you may need to build a custom mounting plate.

Please note, the button plate is posted as a seperate project on Thingiverse. https://www.thingiverse.com/thing:2601312

The shifters are part of the Open Source Button Box project and have been tested with the project's "Wheel Button Box".
