The larger one (by a factor of 2x), it's files all share the prefix "XL_". They still however use the same axle dimension of 3/16in. After printing and assembling the smaller of the two, I found it was so small and fiddly that if it were bigger it'd be easier to operate. Plus a larger one will be more forgiving of looser tuned printers. Machine that drums it's 'fingers' as if it was impatiently watching a slow progress bar. Cam1 and crank require supports. Print 3 Fingers.stl and 1 Finger_no_offset.stl The rest of the files do not need supports. Requires some 3/16th rod and some super glue.
