This follow-focus speed crank works fantastic! Make sure to CA glue the knob to the handleshaft. There is a print-in-place ball bearing inside the crank lug. I recommend printing the threaded handleshaft vertically using a super wide brim. Also print the knob vertical with the opening on the bed with a super wide brim. I would also recommend using a bit of light lubricant when threading in the shaft to the lug as it is a snug fit. Print the crankshaft horizontally as it is in the file. Use a raft and supports. This will be the strongest orientation and allow the ballbearing and threads to work well.
