I tried to print this one, but I scaled it to big... and it was warping a lot. Perhaps printing a mini version?UPDATE: Today I printed a smaller one, and it works like a charm!When I was a child I made slingshots out of wood... Living in a city nowadays (Ghent, Belgium) I can relive my youth by printing them. I hope one day my children will use tools like this to explore their creativity :-). I think it best printed laying down. This will make the 'fibers' to take the force.
