This is my bicone transformation of TomZ Curvy Copter.
It was a little awkward to fill the pieces for shaping it and still protect the screws and springs, and when I started on this I didn't know if it would work, but it turned out quite nice.
Stickering is always difficult on a puzzle like this, with curved edges on a curved puzzle, it was important to get the stencils as accurate as possible first, I often spend a lot of time fine tuning these before I start on any vinyl.
I do love this shape on a puzzle,
Thankyou
