I have a camera lens that I wanted to lay in a gridfinity tray. I didn't find a pre-existing model for my specific lens, so I created this script to generate lens stencils and then subtract them from a gridfinity bin.

Imported the script in Gridfinity Rebuilt in OpenSCAD and generate an STL with the cutout. You could achieve a similar result by using your slicer software of choice.

Example usage for a Fujifilm XF 16-50mm f2.8-4.8

The arguments are: [section height, section diameter, optional second diameter (to create a chamfer)]

camera_lens([ [2.3, 44, 54.3], [13.5, 54.4], [2, 55.6], [8.5, 58.5, 64.5], [27.5, 64.5], [36.5, 75.3], [5.3, 75.3, 69.7], [8, 61] ]);
