This is a customizable quick release plate for Manfrotto 484rc2 ball head. You can add extra width on either side, with extra holes, so it is possible to attache more things to the same plate. This is also my first attempt at using the thingiverse customizer. The "standard" hole is for a Manfrotto 200PL Thumb screw. The "3/8 tap" and "1/4 tap" are to be used with a tap to make a 3/8 or 1/4 thread. The "prosilica" hole is for attaching an Allied Prosilica GC-680 camera. The "custom" hole let you choose the hole size and position. I can add other hole styles if needed. Just ask.No support is needed.
