Nice design. But, not all of the shafts are the same size. Too bad, it makes it a bit wobbly. Plus I would recommend the crank to be 100% infill as when I was turning the small gear, the gear was too tight and the crank square part broke. I had to repair it, but I am sure it would be ok with 100% infill. oh and oil helps to have them turn freely.
