Liquid drops
By tca
Drops of liquid are described by Laplace's equation. There's only one non-dimensional parameter beta that controls the shape of any drop, beta = g rho b^2/T where g= gravity acceleration, rho=density, b=curvature and T=superficial tension.
The profile for each drop was obtained by numerically solving Laplace's differential equation[1] for the corresponding beta value and a simple GNU/Octave script for generating the final STL. beta>0 corresponds to standing drops, for beta<0 we have hanging drops and beta=0 gives a sphere. All the drops have a volume of 33510 mm^2, the same volume as the typical ping-pong ball ;) As a consequence all drops weight almost the same with 100% infill.
The STLs files are for standing drops for beta=1, 10, 100 and for hanging drops beta=-1, -0.5, -0.35

Have fun and enjoy your BIG drops!
