Peephole cover

Diameter door peephole of *.stl file - 25 mm

In the *.f3d file (autodesk fusion 360), all dimensions of the part are changed through the parameters.

Updated the model: in the new version, the cover thickness is 1.75 mm versus 1 mm in the old one.
I did so because a lid with a thickness of 1 mm transmits light.
