Base (standoff) for Amcrest dome cameras

I created these to allow the cameras connections to be hidden under the camera.

Two versions:
110mm for cameras with 110mm diameter base,
this version is flared at the base.
Example: Amcrest IP3M-956E

120mm version (actually 118mm to get it to print) for the larger base cameras.
Example: Amcrest IP2M-851EW.
it does not fit as pretty because of the odd hex shape and funny location of the mounting holes.

both versions have three mounting holes spaced 85mm hole to hole.
