-We used an Ultimaker 2+ 3D printer and the models in the photos are printed with 0.6mm nozzle (you can also use a 0.4mm). We used PLA Real Filament & Ultimaker filament in Silver & Pearl White. -Support material and brim only used on the 'Mama Whale Body' file. -The resolution is 0.15mm - 0.25mm. -Infill isn't needed. - To remove the brim use a sharp knife and file or sand back the brim to the edge of the 'Mama Whale Body' model. -The 'Mama Whale Body' has been designed with a click hinge that the 'Mama Whale Mouth' should snap fit into straight from the build plate, if not you can file back the hinge on the mouth a bit to create an easier fit.
