Every assistant cameraman that has worked on a show with an ARRI 2B or 2C on it has had the experience of taking the camera out of its shipping case, only to notice that the magazine port dust cover is mysteriously missing. In the same vein as the ARRI 16 S replacement cables and ARRI 35 2B/2C pistol grip motor power adapters I have made, I thought that I could spend a day modeling these dust covers and 3D printing a batch. Initially, I printed enough to cover the cameras I have in stock that are missing their original dust covers, but I thought I would offer them to the outside world as well.
The original dust covers are a very simple design. On the bottom of the dust cover is a dovetail that matches the magazine locking dovetail on the camera body, and enough of a rectangular flange to cover the opening for the film port and magazine drive gear. After a couple of hours of measuring and sketching, I created a 3D model in OnShape, printed a couple of prototypes on my Bambu P1S, and after 2 tries, I was happy with the result. So here is my version of the factory magazine port dust cover for the ARRI 2B/2C: https://ln.run/OFgP9
