Steadicam for DC cameraThe STL size for this is huge, so I upload my source file in 123D beta 0.9, and for your easy edit. My design is inspired by lots of gimbal / steadicam made by others, can't recall and mention all of them. But I re-draw it by myself.The dimensions may sometime seem strange, since my printer has a tolerance of approx. 0.5 mm. Basically, all holes are for the bearings and screws mention below (M3, M5 and 1/4-20) You will need the following parts:Notes on counter-weight: I use steel balls to fill in the container, but this approach is expensive. You can use any weight you can think of.Enhancement: Instead of screw your DC directly onto it, you may use a Marco Rail instead. Then you have more control on the location of your DC to balance it, instead of using the turning mechanism at the bottom. and, sorry for my sluggish Enghlish
