This is a derivative of one of the parts from Flummer's DSLR shoulder rig. The "dual parallel standard clamp a" part is too wide to print on a thing-o-matic, so I chopped it in... roughly half... and added the finger joint to join the two parts together. I was curious to see if the stacked halves would print ok, and they do. the finish is a bit rough on the top half. Oh well. You will need to a 1/4"-20 bolt or something equivalent to secure the two halves together, but I've found this to be really stable and rigid otherwise. The fingers are snug and the say the filament tends to be laid down lends a good amount of rigidity when they're stacked against each other and mechanically tightened down.Once the part has finished printing, you should be able crack the support fingers away from the bottom half that were holding up the finger joints of the top half. Then you can carefully take a razor and slice the two halves apart. Warning! Razors are sharp and you can hurt yourself if you're not careful! This thing was made with Tinkercad.
