2-3DQR quick release for 22mm shaft

Quick release for direct drive wheel simulators. It is based in an original design by Racing Mat from xsimulator.net forum. It is improved so can be used as a quick release using a 34.9 bike seat clamp or just attach it to the shaft with one M6 bolt.
Used in my OSW (open sim wheel) system.
