This is a single model, print 2 of them. Slides over each end of the Transmitter, small cutouts to go around the feet, and thick enough so the feet are flush with the bottom side for flat mounting. The front or back has a small lip to prevent the transmitter from sliding forward or backward. Mine has been mounted to the wall in my garage for 2 months now. I printed mine on its side, directly on the build plate and zero supports needed.
The author marked this model as their own original creation.
