The STL files ready to use in a slicer and print are available at this link. (I recommend using Ultimaker Cura)

For those interested in obtaining a kit for assembly or an assembled hull with fin, bulb and rudder,  please contact me here.

Here are some videos of the development and you can comment on what you think in the comments of the videos themselves.
