An honorary thank you medal for our Seneca 7 bike team "mule" who rode the whole distance solely to provide logistical support. (Just imagine Donkey is a mule.)
Medal design traced from a photograph in Inkscape, paths converted to line segments with Flatten Path extension, exported to DXF, imported/extruded/exported to STL with OpenSCAD. (The Seneca 7 medal design is, of course, property of the Seneca 7.)
Medal and Donkey models combined with Meshmixer. Attempted to use Inflate tool to fill in mouth a bit for easier printing. Decimated to reduce polygon count with Meshlab.
White PLA. Slic3r settings: 0.3 mm layer height. 3 perimeters. 4 top/bottom layers. 10% line infill. Supports enabled at 18° with default settings (supports lower jaw but roof of mouth is unsupported and a bit scribbly).
