Sony E-Mount with M3 Screw Holes

This is a Sony E-mount (For Sony Alpha mirrorless cameras) to 5x M3 screws. It's intended for building your own lens. The FFD and diameter is changeable in the openSCAD file if you want to make the mount taller or shorter. The shorter mount is for lens projects you might have that don't necessarily meet the 5xm3 standard (see link below) but you want to use anyway without fiddling around with openSCAD code. With that file, the FFD is set to 10mm, giving you 8mm free to build your lens around. the FFD of the larger stl file is currently set at 44mm and the diameter fixed so that the screw mount is interchangeable with other custom built lenses made to this standard: https://www.thingiverse.com/Solarence/collections/43974549/things .
