This simple Raspberry Pi camera module mount is used in conjunction with a cheap pose-able magic arm clamp. I also use the Pi Camera HDMI Cable Extension modules. These eliminate the need for long flat form cables and allow the use of standard HDMI cables to connect the camera.

The HDMI modules are available here: https://www.tindie.com/products/freto/pi-camera-hdmi-cable-extension/

The Magic arm I found on eBay for about £12.

I'm using some M2 x 15mm hex spacers, anything above 8mm long should work to stand the HDMI cable far enough away from the mount.

You can mount direct without the standoffs if using the flat form cable.
