the Sommerfugel NY-interior cut file is a mistake, you'll have to pogram the Shaper to do an outside cut. I made this cut with the 3mm bit and an offset of 1 mm til i had the decired depth, then i cut 0,5 mm deeper with no offset.
the pocket of the butterfly was made with the 6mm bit, and the the egde of the pocket was with the 3mm bit in the decired depth with an offset of 0,05mm for a perfect fit :)
