Hikvision Dome Camera Junction Box

Needed to design a custom Junction Box for a Hikvision dome camera DS-2CD2145FWD-I(s). Came up with a simple design of a Junction box with a threaded inner side and a corresponding mounting plate for the camera with an outer thread. Thread size 110x4 metric. Junction box has a threaded hole at its back to fit M16 cable pass through (see picture). Box is suitable to be fitted on a metal bracket (L-shaped etc.) or withouth pass through gland on a wall. Sliced file contains a pause at layer 31 to allow for inserting a thin M4 nut (7x2 mm - see picture). Camera then gets mounted to the plate and then it you screw it into the junction box. No gasket needed but you can add some 110x3 ring or flat 110. All holes are 4mm in diameter. To mount the camera to the plate you need 3 M4 screws (standard hikvision provided).
