Customizable Lens Diffuser for Macro Photography

This is a customizable diffuser that attaches to the end of a lens or microscope objective, using either filter threads or a friction fit. When lit from behind with sunlight, a flash or other light source, it provides a soft diffuse illumination for photographing small subjects. Many options are provided to customize the threads and the diffuser shape, and the end can be angled to provide better illumination coverage when the lens is positioned at an oblique angle.Slicer ParametersFor simplicity you can just load the supplied print profile and replace the geometry with an STL generated by the customizer. If you want to set the parameters explicitly, here's what I recommend:QualityNozzle size: 0.4mm works well, but 0.2mm can give a thinner diffuser and more accurate threadsLayer height: 0.08mm or as small as practical if printing threads; can be larger if not using threadsSeam Position: Random (reduces warping in the diffuser cone)StrengthWall loops: 1Detect Thin Walls: yes (otherwi
