Miranda even had PCBWay mill custom heat sinks to help keep the motors cool, which was important to stop them from melting their 3D-printed mounting brackets. Even the extruder was scaled-up to huge proportions, giving it the ability to push the ridiculous amount of filament necessary to form a kayak through a 1mm nozzle.
