Neewer 37mm clip-on ND Filter Case

thingiverse

I received a Neewer 37mm Neutral Density Filter from Amazon for my phone, but it came with an incompatible case. When I attached the filter to the phone clip, the two no longer fit inside the case, making it unusable. I won't compromise on convenience and usability, so I designed a new case that snaps open and shut. It even features a small ND Filter logo for added style. Hopefully, others who purchase this filter will appreciate having a decent case for it. This design may accommodate other clip-on filters with the same shape profile, but no promises. The filter still rattles slightly within the case due to my deliberate design choice - I left some room to insert a felt disc at the bottom. Adding this extra feature is optional, and the case will still protect your filter even without it.
