Dimmer knob for the Senso-series

Here is a dimmer knob for the Schneider Electric Senso series dimmer.
This may also fit for some other dimmer series also.
It is a very common problem that the inner plastic guide of the dimmer knob will break.
After that the original dimmer knob will not stay in place.
This 3D print will fit to the dimmer with or without the original spring.
As there are high voltages in the dimmer, you should use this print with your own
risk and you should know what you are doing.
