This toy is fun but very easy to flip on its back. Now it can rise and walk again!!! Quick print, no support, works even before glue (prob not for long). Snaps on and off the beast easily. http://youtu.be/akZQmbh6YpkIf you print it and love it, please consider donating (min $0.75) by buying my models on Pinshape... Thanks kindly. http://pinshape.com/items/22696-3d-printed-sine-wave-toy-10-pin-version-2016
