Is it waterproof ... YES, it is!

  • Watch the video RC MiniMono Boat - 3D printed Jet Drive UNDERWATER! After that, there was no water in it!
  • If your print of the hull is good, it should be waterproof. But, if you want to be safe, you could still paint it with a thin layer of car clear coat. 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 or with a 3d printed flex seal

OK, thanks.
I ordered the rubber cord, so no need to print "boat_hull_seal".

@macandnews The "boat_hull_seal" was a wish of a user. You could print your seal instead of using a foam rubber cord.
But i recommend the foam rubber cord.
Print Settings:
The Boat 300 doesn't need special cura settings, because the hull is much thicker, so there should be not problems with the standard print settings.
Otherwise, you could take the same settings of the Boat 200

Hello, I'm going to start printing the boat, but I can't see where this part: "boat_hull_seal" is mounted in the assembly video. Is it to print it with flexible filament and replace the sealing bead?

Where are the images of your Cura settings?

Thank you

Hi macandnews, thats an idea. I will do this next time.


Is it possible to have links to buy the parts at Banggood to avoid placing multiple orders and limit delivery times?
Thank you, A +++
