This was probably my most difficult project thus far. While the model worked as intended on my PLA printer, I faced some manifold issues and areas of the model were too thin to print on FDM printers. I reached out to the community on Thingiverse and after a few tweaks the model was ready for FDM printing. Examples of the printed can be seen on the model's Thingiverse page.
"Cousins to the great dragons, wyverns have two scaly legs, leathery wings, and a sinewy tail topped with a poison stinger that can kill a creature in seconds."
