This is a complete shoulder rig for DSLR Cams printed on a Makerbot. After spending much time in development and printing out several tests, time has come to share this great thing to you :)Special FeaturesMount-Plate: The mounting system is compatible with my Velbon DV 7000 Tripod. So i can switch fast beween the tripod and my new shoulder rig.Optical Viewfinder: For sunny days!Follow Focus: I tried out geared ones and also tried to develop some complicate solutions (ff by turning the grip e.g.) but the best way to Follow Focus was a ring with a simple cord! So you can leave your hands on the grips the whole time.All plastic parts were printed on a Makerbot Cupcake CNC Ultimate, ABS Material with Heated Build Platform.Print the parts // I did with ABS at 220° and Heated Build Platform at 110° with good results.1x 500mm dia 16mm (inner dia 14mm) 1x 230mm dia 16mm (inner dia 14mm) 1x 320mm dia 16mm (inner dia 14mm) 2x 250mm dia 20mm (inner dia 18mm)When you put the horizontal tube (320mm) in the t-connector drill small holes into the alu tube through the holes of the t-connector. Fix the tube with metal screws. Figure out the best position for you.Screw the grip clamps onto the grip tubes. In my case they were so tight that i didnt have to fix them. But you can fix them with metal screws or glue of course. Screw the grip clamps onto the horizontal rig tube (320mm)Next part might be a little tricky. I attached a small lens from a childrens magnifier to the viewfinder. I found an old plastic lens in my toolbox that works for me. I put it in front of my eye and i had a sharp view on the display with a distance of about 6 cm.Finally you can attach the hand grips!
