More to come later, I'm tired 😴
This is designed for v1 of the nice!nano. If the v2's dimensions are the same, you'll be good to go. The width of the holder is the same as the popular Elite-C holder out there, but it's 4mm taller. Be sure to update the opening in the SCAD model or whatever you're using.
This is what I change it to for the Dactl Manuform, but please test this before you do a full print.
