Hi
Have you stopped work on this?
I would like to get one for a quad lock, but looking at pictures and fitting the vibration damper I think it needs extending by 25mm and the mount angle flattening so its parrallel with the dash.
It also needs a hole in the center for an M5 nut.
There is one on thingyverse, but it just needs some tweeks.
Iwould rather buy from you if you are offering this.
