I found a couple of ceiling mount brackets for the Ring Stick Up Cam, but they were very flimsy outdoors and shook the image in the wind.

• Re-designed for strength and rigidity
• Included a few mounting hole options, I just use the one single middle hole for ease. But you may prefer to use the extra ones for more strength.
• All holes are M4, including the camera mounting clip holes
• Recommend a stainless M4x10 or M4x12 bolt with a washer for the grey camera mounting clip.

My print settings:

• PETG for outdoor resistance
• 4 perimeters
• 4 top and bottom layers
• 25% infill
• 0.4mm nozzle 0.2mm layer height
• No supports or brim

STEP file included so please feel free to modify to suit your needs :)
