The bigger one's files all start with "XL_". They still use the same axle size, 3/16 inches. After assembling the smaller one, I found it too tiny and finicky to operate easily. A larger model would be more forgiving for loose-tuned printers. This machine taps out its fingers like a clock ticking away. Cam1 and crank need support structures. Print 3 Fingers.stl and 1 Finger_no_offset.stl files. The remaining files don't require any supports. This project needs some 3/16th rod and super glue to complete.
