This mount made for Hikvision DS-2CD1047G2 IP camera. But will work for other models with same dimensions.
I wanted to connect the camera to tiles on the wall, but didn't want to make holes in the wall.
I didn't use original screws provided with hikvision camera as they are longer than needed. I used M4x12 bolts and prepared holes for the bolts with thread tap tool. I think M4x10 will work too.
I printed the part on PEI Sheet using PETG filament and after printing the mount I used sandpaper to make the surface for tape flat.
If you use glass bed or another side of PEI sheet, I think you don't need sanding.
Before connecting the camera with tape I degreased the wall with alcohol (ethanol) and applied "3M 94 Primer" on the mount itself and on the wall, then connected "3M VHB" tape to the mount and pushed it against the wall.
To unstick the mount from the wall later, use alcohol (isopropyl or ethanol). Spray it on top of the mount to let it go under the 3m tape, it will reduce adhesion and you can disconnect the mount from the wall.
The author marked this model as their own original creation.
