This is a junction box for mounting and hiding the cables for a Dome Camera.

It is designed so that there is just barely enough room inside to hide all the cables, making it low profile. I Specifically designed it for the Hikvision DS-2CD2542FWD-IS. It will likely work with other camera models.

Recommend using an outdoor friendly material such as ABS or PETG. However, I have printed 3 of these in PLA, and have lasted over 4 years so far without issue.

I screwed M3 screws straight into the plastic. You could also use metal threaded inserts.
