We've got a RED ONE Digital Cinema Camera at work and the RED ARM broke, and after multiple failed attempts at repairing it, I decided to design a new arm. "CAMS" stands for "Camera Accessory Mounting System" and this is the first piece, which is meant to mount an LCD Display to a RED Camera, but you can use it with anything that uses standard 1/4" mounting hardware.
There's a bit more info in this blog post: http://rasterweb.net/raster/2014/03/05/a-new-arm-part-ii/
Print both blocks, six of the knobs, and one small knob, and add 1/4" bolts and nuts.
The smaller knob is used for the part that attaches to the camera to allow for more clearance when tightening. I used a Philips head screw for the one that attaches to the camera so it could be easily mounted since you can't spin the whole thing around.
You can easily adjust the LCD Display tilting up & down, and rotating left & right, depending on how loose or tight you turn the knobs.
Oh, the holes for the bolts might be a little tight, as I tend to run a 1/4" drill bit through them to get a good fit.
