FlexBall (printed with NinjaFlex)

thingiverse

I bought NinjaFlex filament and was searching for a simple print to try it out. I found this: https://www.thingiverse.com/thing:821858 But the results were quite disappointing. However, I liked the idea of a little ball that can be squeezed, so I end up creating my own version. This was working much better (and my cat like it as well). Attention: The design is quite small, so you probably want to scale it up to make it bigger. The one you see in the picture is done with 250% of the original size.
