The file 'M42 Lens Cap Cover 3D Printer Model' is (FCStd,stl) file type, size is 7.5MB.
A lens cap for M42 mount lenses. I increased the diameter of the thread slightly so that it fits nicely when printed in PETG on my printer. If you have any issues try scaling in xy in the slicer or edit in Freecad (ThreadProfile Workbench required).
