Mount I made to put the BTT SFS v2 on my Q5. Includes a guide for the reverse bowden going down to the extruder.
I printed this out of ASA, with 5 walls and 20% infill. But this part is not under much load so other materials are likely fine as long as you have enough walls and infill to make it reasonably stiff.
The author marked this model as their own original creation.
