Dyson V8 switch ring

This is a permanent switch for the Dyson V8. You need an additional M3x20 screw with two nuts. It was very important to me that you can still put your index finger on the switch during operation in permanent mode. The permanent mode can be switched on or off either by turning the whole ring or with one hand from the handle.

When assembling, the printed part can simply be spread over the filter/handle at the back and slid over it. Then attach the M3 screw and adjust the resistance while turning.
