Here is a triceratops that I designed with TinkerCAD. Print it, paint it, share it. Make it yours, and please post a make.
I use Artooli Extra Fine Tip acrylic paint pens. I use 3 coats of water based polyurethane a day prior to painting. It smooths the print layers just enough to keep the paint from running, and keep the colors vivid.
