FF AD5M Camera Mount for 32x32 board

This mount is intended to fit where the stock FF mount goes (toward the top of the A pillar) but it is designed to hold a 32x32 mm square USB camera with a 14 mm diameter center-mounted lens and mounting holes centered at the vertices of a 28x28 mm square. Mine cost less than $20 at that big river in South America. There are two pegs and two screw holes to mount the camera PCB and one screw hole to afix the mount to the frame. I printed mine with PCTG at 0.20 layer height, 0.40 nozzle, 15% infill and no support. It installs virtually identically to the FF accessory, for which videos are out there. I happened to have some very tiny screws (0.1" D x 3/16" len). Sorry - didn'thave any mini metrics on hand. Likewise for the single screw to hold the mount in place: no 2.5 mm on hand, so I used an SAE for which I predrilled with a 3/32" bit. Sorry if my BOM is sketchy -- but hopefully the model is cleaner than other options out there (which don't fit a 32x32 anyway?) Surely you can finger out 3 screws?
