4G Sprint Boat Build Part 2: Cover Lid

[@emory442]

That's really slick

[@ricardooreamillan3674]

I'm glad it finally works! very good idea! I think I'll do something similar in my next prototype!

[@3dm4rk]

Brilliant idea, keeping the inside bone dry was the biggest problem I faced with the original M-Jet , I ended up using hatch tape in the end. I might revisit the build and try to retrofit something similar! Thanks! 👍

[@RedneckLovinLife]

LMAO!!! What's lighter? "THE WHOLE FREAKING BOAT!" I'm dead!!

[@vasekkeller-kelly5893]

To je skvělé řešení, je možnost od vás stahnot soubor na toto vodotěsné víko,předem děkují

[@mjetdevelopment]

Jo, lze stáhnout celý trup www.cgtrader.com/free-3d-print-models/hobby-diy/automotive/4g-sprint-hull-for-rc-boats-2022 A trochu jiný rozměr stejného víka má nejnovější Ragnarok, s více možnostmi tloušťky stěn www.cgtrader.com/free-3d-print-models/hobby-diy/other/ragnarok-3d-printable-rc-jetsprint-boat

@@mjetdevelopment Děkuji moc je to krásná práce 👍

[@vasekkeller-kelly5893]

Mohu se zeptat jak mate to viko.Chci si ho nechat vyrobit a je možno ramečk vyrobit z petg a viko z tpu.​@@mjetdevelopment

[@mjetdevelopment]

@@vasekkeller-kelly5893 Ano, víko musí být z TPU - doporučuji přečíst txt soubor s vysvětlením u víka modelu Ragnarok, který jsem sdílel dříve. Na materiálu základny nezáleží (jen samozřejmě ne TPU)

[@mjetdevelopment]

@@vasekkeller-kelly5893 Hlavně u TPU pozor na tuhost, jsou různě měkká TPU, proto ten txt soubor.

[@vortkes4684]

Looks great

[@iandrake4683]

Nice design. I like this format. Keep your videos about 5 minutes and no longer than 10. That way I can watch a while video when I have a break.

[@mjetdevelopment]

Thanks for your suggestion! I will continue this series.

[@hjl4004]

Stéphân this is a great solution that undoubtedly will save the required weight. First questions I have is how does the material handle motionfatigue?

[@mjetdevelopment]

Do you mean the TPU? I dont know yet. But I can print a new one once needed. Also it is transparent white so should not be getting too hot in the sun

[@hjl4004]

@@mjetdevelopment excellent design addition! Do you think the intergraded flexible bead design can be made even smaller in cross-section to save even more weight?

[@hjl4004]

How about a hollow bead design? Would that be possible?

[@mjetdevelopment]

@@hjl4004 Yes. I think even lighter and smaller profile design could be possible. I decided to go with this because I still like some rigidity, and the worst thing that could happen would be if the part glued in the boat broke. That would be a very hard repair because the surface needs to be accurate in order to seal

[@rschotman5556]

nice 🤙🤙

[@arm_fpv412]

Your comment on the video where you used the old hull to test the m jet 35 you said you'd be making a longer 50cm hull, is this one 50cm or is it the 39cm m sprint? Was thinking about printing one in anticipation for your m jet 35 but I'll wait for the new hull design if that is coming later down the road.

[@mjetdevelopment]

This is the one, 50cm. I am not planning to design a 3D printable 50cm hull though, things get quite heavy at this size if the hull itself is 3D printed. But I will release the mould files for this hull, together with other things I used to build it. So that anyone can build this hull like I do.

[@arm_fpv412]

@@mjetdevelopment Ah ok awesome would it be reasonable you think to use fiberglass instead of carbon fiber to keep cost down?

[@mjetdevelopment]

@@arm_fpv412 Totally yes. I used fibreglass multiple times before, it is a great option. It is just a bit more flexible, so you need more layers and thickness to make the hull stiff enough, which results in more weight. That is why I use carbon fiber now.

[@dronyri]

I have already prepared the carbon fiber, resin and everything needed to make a new model of the best jet I have ever seen. I am really waiting for you to post the files to make a new version of the detu like yours

[@mjetdevelopment]

Wow! Do you mean files for the hull? I will definitely share the hull files, I could do it quite soon even if my boat is not complete yet. I am glad you like the M-Jet 35! It will still take quite some time though before the small production of the pump will be ready.

[@dronyri]

@@mjetdevelopment yes, I'm talking about the file for the v2 version of the mold to make the hull of the boat from carbon

[@dronyri]

@@mjetdevelopment the V2 version of the matrix is ​​better than the first V1 I'm waiting for the files to be free available (or to be able to buy them) so I can start making the carbon jet body. Сool idea how did you make the tpu cover it's just bingo, easy to close and easy to open. I am waiting for the files to make you a photo report

[@dronyri]

@@mjetdevelopment I already bought files with a 300mm mimi jet and here I am at the finish line and will test on the water. but your jetboat is the best I've seen

[@mjetdevelopment]

@@dronyri Here you go! www.cgtrader.com/free-3d-print-models/hobby-diy/automotive/4g-sprint-hull-for-rc-boats-2022 Just let me know if you need a different file or something is unclear. If you wish to share photos and discuss your build, you can join the official M-Jet facebook group: facebook.com/groups/623045356071128 I would be also very interested to see how your hull goes!
