Nextbase 412GW 30mm CPL adapter Mike Edmonston
Printed this at 0.1 resolution using default settings on Flashforge Creator Pro. ABS 1.75mm filament.
This is a little tight on the thread and the inside diameter to allow for removal of material to create a snug push fit. I used a 3 corner scraper to remove the excess material (a few thousandths of an inch until it pushes snuggly onto the lens.
