35. Custom helicopter fins for Siege Springer I was thinking about this for a while. I'm aware of the 3d printed kit to add fins, but they're really small and in the wrong spot compared to the cartoon. After getting the Shockwave Lab Z Sword for Dai Atlas, I noticed that parts of it would make for good fins. Made resin copies of part of the Z sword and glued on a properly sized tab. Made a resin copy of that so that it's all one solid piece. As I only had 1 mold instead of 2, I opted to cast in black (as I was casting other stuff in black) and then painted after getting 2 copies. Mixed together Tamiya medium gray, white, and blue until I got a match. The fins can stay on for the other alt mode and even robot mode (but not even remotely practical).
