Update 19.03.2023: I have also build one with a 45 degree angle as the cam itself has not that much movement options.

I built this mount so I could attach the HelloBaby Monitor Camera to our playpen. Really simple designed and should be printed as in the picture, then no support is necessary

I printed it in PETG, but can be printed in PLA as well

Print settings:

Material: PETG

Supports: No

Layer height: .2

Infill: 15%
