Nauticam introduced a filter holder for MFO-3 to protect the surface glass since they "intended" not to add a small hood for it by default🤣 57$ is pretty much pricy for such a small stuff, so I make this ligher version by 3D print, couple bucks of even cheaper if you have a printer or someone can help you on it.

It contains 2 parts: Inner ring by TPU, it can be stick to the lens with that circle groove; the outer part is built by PETG or PETG-CF, it is ligher bur durable to protect. the upside is reduced to 82mm so it's easier to have a lens cap on it.

I can upload the STL files if needed

Can any admin change the subject from "Light" to "Lite"? A stupid typo😂
