I needed to mount a Blink Mini camera to a window, the available models looked heavy and overdone so I whipped this one up in Fusion 360. I used a bit of double-back tape to attach to the window, holding so far. Tape on Amazon: https://www.amazon.com/Teskyer-Double-Adhesive-Multipurpose-Mounting/dp/B096WYFQM8/
Fusion 360 CAD Model file included along with step for remixing.
I printed in ASA for UV resistance and higher temps.
I used organic supports in Prusa Slicer 2.6 by using paint on to prevent the sidewall holes from getting auto generated supports. See the slicer image. This may not be the most efficient way to print but it puts the support interface scars on a part that doesn't show.
The 3mf with SLICER in the name has the paint-on marks applied.
I recommend that you cover the LED with a couple layers of electrical tape, in the dark it causes issues with reflections in the glass.
UPDATE: I think this might be a much better way to print (on the “top” using support enforcers) SLICE-2:
