Some people requested the 50cm hull files from my M-Jet 30 video. Here it is, but keep in mind: The design of the mould is by far not the best way to make a mould. My final hull works great, but do not except the mould design to be as refined and tested as the M-Jet pump. There is no manual included, only the video about making the hull.
Update 23.11.2020: Step files for the hull and mould together with a pdf drawing were added.
