So now I've finally got myself the touch controllers and obviously had to make a design to mount them on a wall. :)
I've tried a few of the ones on thingiverse but none were to my liking, either too clumsy or not secure enough. This one is small m, quick and easy to print without support, doesn't take up much space and offers a more secure way to mount your controllers on the wall.
EDIT: Upon request I've made a versi9on with two mounting holes.
