Remix of Shira's AWESOME design. https://www.thingiverse.com/thing:1458545 Thanks Shira!

Since the original design is very nice modeled, but lack in fuctionality due to a too tiny ring, I remade it with a taller strike plate and separate, bigger ring with a more dense infill (+45%) to make it heavier.

The head must be scaled 70%, print the ring and the strike plate as is (plus support). The ring (part A and part B) must be assembled with the two alignment pins (cube and cylinder) , inside the mouth of the dragon
