The original Beyblade spinning top. Peng-ee A.K.A. Kenkagoma Koma

This is one of the toys I played with when I was a kid. I saw kids playing with "Beyblades" which reminded me alot of this. Hence I've decided to visit the old memory lane and make this. Works well. This guy does pretty good job of explaining it.

UPDATE
Friend's printer had hard time making cap that will fit into the top. So I've made some changes in the new one. Try printing at about >40% infill. I tried doing it with 20% and it's just too light. Can't use it for battles when it's too light.
