This is a filter that you put in front of your lens to have a Petzval effect. This is an OpenSCAD script. The STL files here are 60mm and 67mm internal diameter. Adjust the diameter of the lens you want to use, render (F6) then export the STL file. It take me a while to export the STL file for me, don't understand why. Just be patient. Play as you wish.
