thingiverse

Combustion Lid, body and nozzle design for a bipropellant engine demands precision and attention to detail, particularly when it comes to injectors and cooling systems, which are essential for successful ignition. Avoid using plastic materials unless you intend to create a decorative model or desk piece, as they may not withstand the stresses of combustion.
