ADHDv3 Car Window Antenna Mount

Having gotten bored one day and fueled by too much Arizona Green Tea, I set out to make something that I had no idea I could actually make: an antenna mount that brings the cable inside, through the window, and works for both (RP-)SMA and magmount devices.  Specifically, for WiFi antennas for the great World Wide War Drive (yes, wardriving is still a thing! https://wigle.net).  Even more specifically, this is for the rear windows in my Ford F-150, explaining the precision 30 degrees tilt to the window/antenna base interface.

The big indent is for a 1.25" fender washer (part code UDC at your home improvement store) and should be epoxied in place.  This is for your smaller magmount antennas.  For safety of your antenna, there are two through-holes for use with zipties to keep the antenna in place.  Seriously, don't put anything big on here.  Or even medium.  Half pound / 225g at most? Please?

The smaller hole is for an (RP-)SMA bulkhead mount for your (RP-)SMA antennas.  Same as above, nothing too big please?  15mm thru, 6.5mm threaded, and 12mm washer/nut diameters fit even the larger SMA bulkhead connectors.  The backside works with thin (1.33 and 1.95mm) coax assemblies and in a pinch works with RG-316.

Apply a couple layers of copper tape to the washer / SMA connector side if you want to have a good ground plane for your antenna.  You kinda need this, unless your antenna specifically says it is “ground plane independent”.

Still there?  Cool.  I suggest printing in PETG (or PLA if you like to live dangerously) with four vertical shells and 25% infill, preferably rectilinear.  Keep it on its side as delivered, you want that layer strength.  

Use at your own risk, I assume no responsibility if you print it weakly and it breaks off and damages anything.  Good luck and WiGLE all the things!
