Wolfie: supports free wolf cub sculpt

A sculpt that took a day and a half (from research, preliminary sketches and sculpting for multi and single extrusion versions plus a test for single). I've included one of my sketches as I find having my ideas down in 2D form first really speeds things along. Designed to print scaled up and down. This example was printed in Sirayatech Fast resin on my Prusa SL1 but this model will print well on and FDM machine too. Multi extrusion version to follow.
