This is a work in progress. Most pieces go together easily now with little or no finishing, but the spring cover still needs refinement.

Printing

The boat prints in spiral vase mode, with the intention of making it hollow, lightweight, and watertight.

The gearbox, shaft, and prop are meant to be printed in the traditional manner (not vase mode). Unlike Mike's original shaft model, this shaft is meant to print on its side. It's stronger in that orientation and easier to print well.

If the newfangled Arachne perimeter generator is used, then for a good fit, ensure that its minimum feature size is set no less than its minimum perimeter width.

Assembly

As with the original, no fasteners or adhesives are required. Assemble as directed in Mike's video.
