3D model description

Rear lens cap for Arri S (Standard) lenses. A couple of versions included, 25mm deep for lenses that don't protrude beyond the back of the mount (mostly 35mm lenses) and one 40mm deep for 16mm lenses. With Arri logo or plain..

Arri B (Bayonet) lens cap: Again, a couple of versions. The single part (v2) may awkward to print with FDM printers (because of supports). So a piece with a separate top, that can be glued or melted on, is included. (It should also be possible to print the open shell and one of the "cap" versions together as one piece, eg in Cura)

3D printing settings

PET or ABS are best because they are flexible.
FDM: The plain Arri-S versions can be printed facedown without support. The two part Arri-B, you might print without support, I found I had to sand the inside (PLA) a little as it was tight and I had to remove the lines left by the printer. For FDM printers it might benefit by being printed very slightly over-sized (I may include a STL to that effect if you can't resize).

Because I'd made versions with flat tops and logos both inset and raised.. there were just too many versions! Plus I think you can print the "open shell" and "cap" together as one print in say Cura, so you can mix and match to get the version you want. However I will add the STL for the 50mm deep bayonet with inset logo)..

Hi there, just purchased this, why not adding the ARRI logo on all of them? I need the 40mm caps for Arri standard and it doesn't have the logo on it, absolutely no big deal, just would've been fun to have it.
