This is my solution to the Hanayama's Cast Coaster. It is a 4 star puzzle and for this particular design, I think they have nailed the difficulty to be just right for the majority!
The solution is actually very swift in motion, only takes around 10 seconds to solve. However it took me a few minutes in the video to make sure viewers know which piece is which, in order to successfully solve the puzzle.
Hope this video helps, and please subscribe if you find it helpful! Cheers!
