B4 Mount Caps
grabcad
Caps for B4 mount cameras and lenses. Pretty much all ENG type broadcast cameras use this mount. I've removed all the embossed logos that were part of the original design as they are specific to my company. There are several different versions of the cavity cap; one is unibody, two glue together and one screws together with a short M3 screw and nut. You must be careful with the underside of the cap as you would not want support material remnants falling onto the camera sensor. Supports may be needed for the lens back-cap flanges, but just on the tips.
