I made this for my Allsky camera enclosure. Holds the RPi HQ camera in place, and puts the dew heater ring surrounding it. The dew ring just clips on. The entire thing can be held together with M2 *12 bolts, or as I have done, bolted the entire cradle to the lid of my Allsky camera enclosure. Sized to fit inside a 4.5" (110mm) clear dome.
