Would it be possible to make room for an ND filter (Runcam orange 5 can use the TBS nd filters made for session 5 cam's)
By making a small lip around the front edge, the filter will jam infront of the RC 5 :)

yes id like that also

Hey guys, I'll be working on this item soon. Does anyone happen to know how thick the filter is? I'm seeing 2.5mm online but that seems wrong..

hey thanks a lot I have a camera butter nd filter here that measures 1.6 mm the actual glass is a little thinner but there is a reusable sticky pad on the lens but I still think 2.5mm would work and still be useable for thicker filters
