I downloaded a dolphin model from grabcad and then flexed it to create the curved dolphin model I was wanted to make. I uploaded it to shapeways and here's a screencap of where the thin walls are and where they need to be fixed before printing. I am trying to print this dolphin model at a very small scale (0.6-0.75 inches in overall length) What would be the best way to go about thickening the fins, nose, and tail? I have tried editing the original surface sketches, but it only increases the base thickness from the fins. Should I attempt to use the thicken feature here? Thanks in advance!
