I tried both variants and it works very well. - The drive shaft of the boat is sealed between two plain bearings with a lubricating seal. - The cover is sealed with a 2mm cord of foam rubber Update - 20190702 added splitted boat hull for printer with smaller build volume height. - 20190708 I'm working on a How To Video and Tutorial to assemble the Jet Boat, but the most should be self-explanatory. - 20190712 added pictures of cura settings and assembly - 20190721 added a boat cover with a changed coordsys, some slicer had problems - 20190806 added a boathull version without 18650 battery mount - 20191027 update boat_hull, nozzle, seal (optimized water inlet of the jet drive, bigger and optimized hull, optimized nozzle and clevis, new 3d printable hull seal TPU filament) = ###[discover my other designs](https://www.thingiverse.com/jtronics/designs) ------------------------------------------------- Website: http://www.jtronics.de/ Instagram: https://www.instagram.com/jtronics.de/ Youtube: https://www.youtube.com/jtronicsTV Twitter: https://twitter.com/jtronics2 Facebook: https://www.facebook.com/jtronics.de/ Thingiverse: https://www.thingiverse.com/jtronics/designs
