gopro steadicam with mostly 3d printed parts
So the current design that I was working with was a failure. The axles are too small to be reliable/robust, so I think I will need to rethink my design and probably use metal axles, which also means I probably should just design it to use bearings at all rotation points. Or at least delrin bushings to reduce friction.
So I'm back to the drawing board on this one, but failure is a part of learning.
These are the bearings a decided to try. They are 608, and are about $12 off of amazon. They aren't super smooth, but I talked with a skater, and he said to clean them and oil them and they will work much better.
I'm currently taking a 3d printing class, and we get to design and print something as part of the class, so I designed this 3d gimbal that will be the control handle for the steadicam. My goal is to print it all as a single unit, and then you snap away the supports to get it to move. I'm still working on exactly how the pieces are going to be printed, but have the gimbal functionally designed.
The blue in the picture below is an ordinary skate bearing. I'm using some Bones Reds because they are pretty cheap and have really good reviews on amazon.
