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

Download the full packet again.
You could download the bought project so often you want, with all updates.

How can I download "20200603 added motor_180_ adapter.stl"
Full packet I downloaded early.

@joengelke
- print the screw with a smaller hole, there are some settings for better results in the slicer software
- grind the shaft flat in place of the screws
- use some glue

I have problems connecting the propeller to the shaft. It is working for the first few seconds then it is turning losse. Do you have an idea how to tighten the set screws or is there another trick to tighten prop?

@giacomoborghi02 I added a link to a lipo charger

@giacomoborghi02 the "boat_cover.STL" file in the v001 folder. It's the old version.

The problem was the ESC configuration.
BLHeli has solved the problem :)

@martijnsan Thanks for helping @Mc_KaNaN

@ Mc_KaNaN swap any two motor wires to reverse direction.

When accelerating until it reaches 50% of the travel, the motor does not move, but when it reaches 75% it begins to turn in the opposite direction.
Any idea?

Hi Stefan, I answered you via Facebook.

Hey Jtronics,

thanks for this design. I have printed the boat_hull.STL in the v002_stl Folder with Cura 4.5 / Ender 3.
The print turned out fine, but there is an issue at the bottom of the jet inlet.
The wall thickness there is so small, that Cura seems to have problems slicing it. It turns out asymmetric.
The Option "Print Thin Walls" changes the issue a little, but it is still visible.

Please have a look: https://www.dropbox.com/s/qrf5uo8elz9qry7/Jet_asymmetrisch.jpg?dl=0

I have sliced with same settings the V001 Model. There is no issue, the jet inlet looks symmetric.

Thanks,
Stefan

I have slice

Hello Martijn,
thanks for the info. I checked it. Yes there was a bug in the parts "boat_hull_split_a" and "boat_hull_split_b" .
But now it is fixed.

Thank you
jtronics

Hello, thanks for the great design. I'm having a lot of fun building together with my son.

Question: we've printed boat_hull_split_a and boat_hull_split_b from the v002 stls. However, the b part is slightly smaller on the mating surface of the a part, it doesn't fit... I've measured the stls in a cad program and they are indeed different.

Could you please release a new set of files that match?

Thanks a lot.
Martijn

Please what support in cura do you use?

What's the difference between v001 and v002? It's not clear from the discription

What's your problem? The links are working.

Could someone pass me the purchase link of these two components on AliExpress?

1x servo brass tube OD 2mm, ID 1mm (servo rod), Length 10mm
1x drive jet bearing, brass tube OD 3mm, ID 2mm (drive rod Length 3mm, servo rod Length 10mm)

Okay :-).Thanks for the rapid answer! Until Yesterday it was also at Aliexpress not available. Thanks god a lot :-) . I have a further question. Is it possible to link your Cura settings? I know you could have an other printer. But I have overtook your settings from the Images. But what is confusing for me. I have in the same Print-Time the twice in filament consumption. And I can't find out why....

@KASU01 The "GS-2502 Nano Servo 2g" is avaiable. The part is linked. Please look to the part list (1x servo GS-2502).

Dear Team,

is there an alternative servo avaiable for the GS 2502 which fit's in the holder of the hull and in regard of the specs. Because the gs2502 is not more buyable in the online shops. Perhaps you can give me a hint. I have tried to find one with nearly the same dimension, but it's very difficult.

If Iook in the comments, it seems there is no support since a longer time ?!

Hope you ca help and answer me please.

Sería posible un plano de conexiones de los componentes? En el video no se ve claro donde va soldado el DC converter. Gracias!

Hi ,
May be it is out of subject question, what is the program you used to generate the animated gif of this model

Hi, the holes are for additional parts like fins or trim plates. But in moment I found no time to test these parts. I will update the print settings with more details.
Not to fast 30mm/s, to get a good layer connection.
not to hot, because of dropping nozzle PLA 205*C
15% infill
walls before innfill & Ouline walls before inlines

Great Project, and thanks for sharing. I've bought it yesterday. Why are there 3 holes on the back on every side? The jet stator doesn't need them all? And are there any other print parameters like Infill, speed. And do you also have a 0,4 Nozzel and regardless 0,35 from your pictures is correct?

PS: A version with swappbale batteries would be great

Having real trouble printing the hull on an Artillery Sidewinder - keeps failing on the really thin part where the waterproof sealing tube goes - is there anyway to amend the file to reinforce this slightly ? the rest of the hull prints perfectly - I am using Prusa Slicer so that maybe the problem

Quick question what do you use to charge the batteries ?

I didn't receive a message. you could also contact me on thingiverse, there you could send pictures.

Hi, I think you forgot to contact me :-(, I send you chat messages to your FB account regarding the strange lines on the hull

Bonjour,
J'ai une radio 2 voies à volant avec son récepteur 6v que j'utilisais avec une voiture RC et j'aimerais savoir si je peux m'en servir pour votre bateau RC.
Merci,
A+++

Podrian recomendar un mando de control y receptor? video del ensamblaje de la parte electronica? gracias

Please give me your e-mail? I will contact you.

Hi have some strange lines on the hull, try S3D 4.1 and Cura 4.2.1, same result.
Printed in Prusa I3 MK3 and Ender 3, same result!
you see it even in Cura when you preview the slicer
any suggestions to resolve this?

Muchas gracias por el vídeo del ensamblaje, me gustaría saber que mando de control y receptor podría comprar y que sea económico, y si es posible añadirle un chip para cargar las baterias. gracias!

Por cierto faltaría el enlace a un mando de control, a poder ser economico y compatible, gracias!

Hello alopezrobles88,
Last weekend, I printed all parts again and made a lot of video material of the assembling. I think the video will be ready at the end of the week.

Un proyecto muy bonito y divertido, espectacular. El fallo es que no venga con los planos de montaje de toda la parte electrónica y mecánica, para los que no sabemos de electrónica iría muy bien para poder realizar este proyecto y disfrutarlo con los mas pequeños de la casa.
