This is a remix of merongi's design. I was only able to recover the E-Mount section in my CAD software as the STL had some issues, so I rebuilt down from there.

This model includes a 1.25 filter adapter right on top of the sensor cover so it should cover all small format pro cameras. (Designed for my ASI533MC-Pro)

NOTE: Bayonet mount does not conventionally lock, but instead friction locks tightly. On full tighten, the camera is upside down in relation to the top of the lens which is not a problem for me. Please feel free to remix further.
