Fair warning: I am a complete novice in 3-D printing. This will, hopefully, be the first thing I've ever printed.
I want to make a Constant Velocity Joint for a camera stabilizer I'm making. I've been looking at different options, and it seems that a double cardan joint would be easiest to design/make/print. However, the intended use involves force being applied along the shaft, into the joint, which I think in a double cardan will cause "buckling" (forcing the joint into a 90° zig-zag).
Also, perhaps I'm wrong, but I don't see it rotating very smoothly (pretty essential for camera stabilization.)
So my next idea is a Tracta type, with bearings. The question is:
Can you print bearings inside their housing? or do movable parts have to be printed separately?
