Arrow fletching marking jig (parametric) - Pin Nocks

Remix of the brilliant design by @ShionS_271443 to whom go all credits for the excellent work.

This remix allows the jig to be used with arrows fitted with pin nocks.
The pin snugly fits inside the opening at the bottom so that the arrow cannot spin when using the marker.
The pin nock should sit flush with the base, as a guiding factor that the arrow is fully inserted.

Please refer to the original model's description for further details on how to set the scad file up:
