I designed this for my F10 M5 and Escort Max360c radar detector, but I'm sure it will work on other makes and models along with most current Escort detectors.
This allows you to tuck the detector up close to the roof right between the rearview mirror and visor. I used a mirror tap from https://blendmount.com/power-cord-mt-series-patented-15-inches-long-rj-11-2-amp-inline-fuse-with-military-grade-taps-080-wide-tap-x-525-lg-mt-4015/ to make for a clean wiring job.
PLA and PETG will NOT survive in the sun for long. I printed this in nylon and has held up for 2 South Carolina summers so far. I'm Sure ASA or some other high-temp filaments will work as well.
You will need to steal the magnet from the factory Escort suction cup mount. Just mount it in the rectangular pocket of the mount then cover it with the factory cover sticker. Use some good double-sided tape on the back of the mount and stick it to a clean windshield. You will have to determine the optimal position. Too high and it will be difficult to access the buttons and difficult to remove the detector.
I have included .stl and .step for versions with and without the ///M logo.
