Organic benchy

Redesigned benchy in organic style. 

Authors:

Based on the shape of original #3DBenchy, but designed fully by me.

Supports:

Not nessesary, but if you want to have better benchy's roof use organic supports.

Layer height:

Best at 0.15 or lower

Nozzle:

Best 0.4 or 0.25, because of narrow connecting.
