Blackmagic Pocket Cinema Camera BMPCC SmallRig USB-C cable holder. This is a remix of a version I found elsewhere, but the orginal version didn't stop the cable from pulling upwards, and still putting presure on the camera USB-C port. I've closed the 4th side in, and left it thin enough that it doesn't interfere with any of the HDMI cables I have. If you find your USB-C cable is too tight, just add a negative part modifier on the top edge in the Bambiu Studio. Too loose, do the opposite.
