About this 3D model
Since I wanted to use the old lens of my granddads camera, I needed a body cap for the old camera body. I could not find the original one and quickly designed a new one in Fusion 360. The camera has a M42 lens mount and was manufactured by PENTACON. Therefore I embossed the Logo on the front of the Cap. I also added a version without any Logo. Link to the Fusion360 file
