1. Make the 3D printer safer for children by blocking direct touch to the metal part of the extruder.
    • A hollow, aluminum cylinder will fit right around the metal extruder.
    • The cylinder should be aluminum since this metal conducts little heat.
    • No part of the cylinder should directly touch the metal extruder.
    • The aluminum cylinder should be just 1 mm higher than the end tip of the extruder.
    • This is a very cheap solution that should interfere with the printing process, yet prevent young children from getting burnt.
