This 212cc is built based on brick built vacuum engine tech, but unlike similar brick built engines which typically come in at 40cc range, it is actually full sized! The video build tutorial will be posted on my YouTube account @CRS_Engines soon. This project will take 1450g / 1.5 rolls of filament to complete with all accessories. This should go without saying, but you will need to remove lots of plastic, sand some areas, and keep the engine on full throttle for a bit after first assembly to wear down seams that affect fitment.
