Allsky camera housing for RPi HQ-Camera

This model serves as an enclosure for an all-sky camera

A distinctive feature of this design is its inherent waterproof quality, achieved without reliance on additional sealants such as adhesives or silicone The dome is meticulously secured between two TPU sealing rings, effectively precluding any water infiltration Furthermore, the screw fastenings are ingeniously engineered to be either completely concealed or accessible exclusively from the underside

During the printing of the sealing rings, it is imperative to ensure the absence of any protuberances at the nozzle's initiation point

The enclosure is designed to accommodate a Raspberry Pi HQ Camera, which secures onto the main plate via standoffs A Raspberry Pi board may be affixed either vertically, suspended from a dedicated bracket for enhanced port accessibility, or horizontally, positioned beneath the camera using spacers; pre-drilled holes are provisioned for this latter configuration

Furthermore, the primary board incorporates small apertures designed to house three ceramic resistors, serving as a dew-point heating element

The following glass dome was utilized for this project:

and seamlessly integrates into the designated recess

For the camera's standoffs, M2.5 size components were necessitated, secured on the upper surface with corresponding nuts

All other fasteners are M3 screws The threaded inserts are specified as M3+4+4.5, with a total requirement of 21 units:

Five for the lid

Five for the main enclosure

Five for the base cover

Two for the vertical Raspberry Pi bracket

Four for securing to the camera mount

All components were fabricated using PETG material
