When using an automatic lens without it's camera, it is useful to use an aperture ring to ‘stop’ the lens down. In this model, I took a step down ring and imported the STL into Shapr3D. I then closed off the top of the lens and created an smaller aperture. This will decrease the f/stop from it's native f/1.8 to ~ f/2.1.
See gcode file for most accurate printing. Set for ultradetail and better centered than the 3mf file
