The utility 3D printed ship is here! this is a combination of everything I've been looking for in a mid sized to large ship. Featuring twin screws and a deep draft its definitely designed to move some water and pull a canoe or something across a lake! The thick walls allow for plenty of abuse and hopefully survivability in some of the toughest seas. Go ahead and make one!

I printed the Hull but something is really wrong.

I download all the files. scale it all down to 85% -- my printer can only print max 20x20x20.
So to scale down to 85% the biggest part is 17cm.

I save the STL file in Gcode as this is what i need for the pinter.
But i see now the parts dd not print 100% even when the printer tell me its done!

I check my stl file all looks good.
I check the saved Gcode file.. there I see the object is not full. why???

at this moment i cant print it.. as when i check the saved stl file - G code.. its not a complett object . example the bow of the boat the stl file I save is 17cm.. I save in g code and go to print.. the prnt then stop on 10cm... and tell me its finish :/

I just wasted 1kg of PLA.... and 90 hours...

I had this happen to me a few weeks ago on a print; it would stop very shortly into the print and tell me it was done. It turns out, I had run out of room on my SD card, so only part of the file had downloaded to it. I just cleared out some old files, redownloaded the gcode, and it ran perfectly after that.

what scale should i print for 2205 drone motors?

How many rolls of filament did it take ??

What was the total amount of filament used for this beauty?

Whats the minimal size bed needed to print this at 100%? thank you

As far as I download and look on all the models in cura.. you need 25x25x25 to safe i think. my printer is 20x20x20. But i did scale down to be 100% sure... But my print failed really bad !
objects looks good. but printer do not finish them... even when it tell me its finish.

can anybuddy share the pdf for the deck, please?

Can you make 3d printable hull/deck, it would be awesome!!

Hi I love your project. Have you thought of doing the sections with deck in place?

what about the little one?

I love your work peter, you're the best!

It's a shame that getting parts for rc boats is such a pain. Does anyone have a good source? Also, does anyone know why most manifacturers make the shafts out of plain steel knowing that it will rust?

use zinz spray on the shaft. anyway a nice clean after every use is a normal rutin anyway.
it wont rust.

Does anyone have any input on motor sizes for a 125 precent model? Also props and prop shafts. I have no model boat experience just rc trucks :))

No chance really, unless you modified all parts to your own specifications by buying all electronics beforehand and measuring them all out. Why do you need 125%? Surely stock 100% is perfectly adequate!

Got bored was just going to make one as big as my print bed would go

He said in his video, buy staineless steel prop shafts from eBay/Banggood, and advised 45mm brass m4 props. Motor size is also said in his video, and other electronics are simple and I you owwwn preference

Ditto... this has inspired me to get into RC. The last RC "anything" I had was 35 years ago with a couple of Radioshack toys.

Any build help would be appreciated. Suggestions on shafts, brass rod, etc.

I'm printing parts like crazy... the hull has been 50 hours of printing so far! I'm printing the bow as I type... 28+ for that one alone.

whats the progress on this project so far, any issues?

All parts are printed and I'm working on painting. I've cut the hull from paneling, but still need to cut a hatch in the back. The only issue is finding time...

I also started printing the "Footy" sailboat. But that's a topic for another day.

What scale did you print that smaller one in Peter? I am attempting to do a 30% version and was curious. Is there a chance someone could come up with the deck in a modular 3D printable way?

learn 3d design and take the measurements from the pdf in the youtube comments, shouldn't be too hard

what scale is the little one?????

Hi Peter! Im collecting all boat enthusiast in my new group "Maritime", feel free to join.

Thank you for the designing and posting this boat. Been a fan of your work for years.

What slicer are you using? Can you post a screen shot of a hull's settings (I'm doing something wrong)? I printed Hull 5 without an enclosure and it I like how it came out, I used almost a whole 1kg spool. Used a taz 5 and Cura Lulzbot edition with default village plastic ABS setting.

I would like to remix hull 5 into a towboat bow so I can push barges around in lakes. (mobile rocket launch pad, tinywhoop bonus gates, foating runway, RC car ferry, etc) I need a floating platform and this perfect for my project!



His slicer settings will be unique and beneficial for his 3d printer. Unless you have the same, i'd advise start with printing benchys and modifying particular things as you go until you get the best results

It's a little on the large-ish size for a 200mm printer, i scaled mine to 80% to make it still quite large, but all the parts fit quite comfortably on the print bed. I think the only real change to running gear is i'll have to drill out the channels for the shaft tubes a bit. Done printing the hull, now doing all the superstructure bits! This is a great model, I love the look and styling. Can't wait to get mine in the water :-)
Printing everything in Inland PLA, 20% infill, except the rudders, which are 80% for strength.

I am just printing it at 100% scale in PLA, I have so far only printed the hull 5 section which has taken something like 23 hours to print at a layer height of 0.3mm and an infill of 20%. I am am using the slicers defaults of 3 top solid layers, 3 bottom solid layers and 3 outline/permimeter shells but just this front section alone weighs an awful lot. Can I ask what settings you are using? I started off using Simplify3D but because of issues with the hull 1 section I am just switching over to Cura and so will likely re do hull 5 again.

weight is good, saves on other weights required to get it to the waterline

is there a hardware list for the props, shafts, etc? wanna know what sizes to get!

watch the end of part 2 (youtube video)

Loved the Video on your channel. What did you use to design this?

I'm pretty sure he uses Fusion 3D by Autodesk.

What scale did you create the ship in if any?

Apart from the little one, 100%

Ok, I definitely want to print one of these now! This is awesome and one of the first scale ships I've seen that a user can 3D print. Any idea what size I should reduce it to get it to be 1/96 scale?

I printed mine at 55.2% to get 1/87, or an approximation thereof, and it seems about right

Hi mate, I am half way through printing the hull and came across a problem with Hull piece #1 the very back part. I am using siplify 3D for printer software.( dont think its the software) the stl looks good but when going to print some of the walls dont show up? its on both sides next to the rudder.. its like its a pocket in the model. any idea what this is?

hmmm strange? do you have a pic of the model in the slicer software?

Emailed some pics to you.. After reading up a bit.. it seems the issue is caused by Simplify3d

same problem --> https://tools3d.azurewebsites.net/ --> problem solved

I have a lot of lead weight i'll be happy to trade for the two boxes of 22 ammo.

Roughly how many hours did the print take?

depends on the printer and print speed, about 20+ hours per hull section

Wow this is so cool! Definitely gonna build this!

I watched your YouTube video, nice design buddie.

Whats the largest part, do you know? I need to see what scale I need for them to fit on my bed.

The largest part seems to be Hull 5, from what I have loaded in my printer software.

just stumbled about this in my thimeline and then realized it´s peter from flitetest :D

This is awsome. Any chance of makeing one half the size but still able to be rc


Ill see what I can come up with after its done printing

That's would be awsome thanks

Need a bit more ballast, seems to roll to easy for a "tug"

And you need some 3D printed props...or are they not strong enough?

i know of others attempting 3d printed props in the past, far weaker and very difficult to print adequately balanced and so often very unreliable

he using brass props

Looks cool man! Keep the up the good work!
