The file 'HDZero 20 Degree Uptilt Mount For Directional Antenna (TrueRC X-AIR MK II) 3D Printer Model' is (stl) file type, size is 50.4KB.
This is a modification of this model form printables: https://www.printables.com/model/464820-hdzero-walksnail-vrx-mount-20o-up-tilt/files
I've modified it to be wider, and include a channel for the wiring to run through the back of it, to allow for a solid flush mount. (The 3d printed stock mounts that came with it, put too much pressure on the antenna wire and keep popping off.)
To print, you would just print 2 of them, but mirror one on the Y-Axis in the slicer.
