Owl Facing Left - Negative Mold for Low Melt Metal in ABS Casting

This is a basic mold for casting the Owl Statue Facing Left in low melting point metals like Rose's Metal (208F), Field's Metal (144F), etc. Make sure to use an alloy that won't exceed ABS tolerances. I recommend high quality "natural" ABS with no dyes/colorants. You can soak off the ABS using hardware store grade Acetone. Give the metal plenty of time to cool as it can take hours to reach room temperature. I recommend printing the mold with ~6 perimeters, 30% infill and print slowly with no cooling fan for best interlayer bonding to minimize cracking as much as possible. My first attempt, a 4 perimeter mold with 20% infill resulted in molten metal leaking into the interior infill space. Most of the 5 perimeter 30% infill molds for this and other models I've made have gone well, so 6 should be about perfect. Have fun and keep it safe and sane. Hot metal can cause severe burns VERY quickly and solvents are flammable and potentially poisonous and need to be handled appropriately. Do your homework first.
