3D model description

Helios 44 lenses are quite famous in the world of "manual lenses" for their swirly bokeh.
A mod has been proposed by Jason Bognacki to create extreme swirly bokeh.
It consists in reversing the front lens.
However, when reversed the front lens comes into contact with the second one, which is something I do not like as it might damage the coating.

This thing is simply a 1.4mm thick washer used as a spacer between both lenses.
This makes a very safe and reversible mod for your lens (see video) https://youtu.be/_sEXubrUupA
