Generic touch-mi support for Creality

I added this bloc to the very famous "Bullseye" ducts for my ender 3. (https://www.thingiverse.com/thing:2759439)

I realized it is not allowed to remix this design, so I just give you this part, that can be fitted left to the Bullseye base creality one.

The fusion 360 file is attached, so basically you can open the STL of Depetsel (2759439) and join this addon to the original design to get the printed.
