This is hole plug for Hikvision cameras junction box like DS-1280ZJ.
You can use it to close openings on your junction box.
You can print it without supports, better to use 4 wall loops and 40 - 60% infill. I recommend printing from PETG. In case of placement in the sun from ASA material.
It is necessary to supplement with a ring seal with an inner diameter of 24mm and a thickness of 2.5mm
