1/144 Nautilus Typhoon 3d printed

[indy1010]

I started working on the ballast.
It will be a 1 liter piston tank. I will be using a NEMA17 stepper motor.
It will be controlled by an ARDUINO UNO
I started making the piston with 2 o-rings. Problem, either the water passed or it was impossible to slide the piston.
So I printed a new piston for hydraulic seal.

I printed a piece of motor support and limit switch support



and the closing plug with the water intake

Well,
I tested a cap with a coat of primer, a coat of paint and a coat of varnish.
Cap printed with 20% infill.
I mounted it on the wtc and put an hour in the water. All went well. Not the slightest trace of moisture inside the tube.

By the way: Any one knows the distance between shafts in the motor mount in ENGEL's THYPOON?

thanks Nate,

I printed a test cap and I will try.
I have a wtc with an id=84mm. I bought o-rings with an od=84mm.
Unfortunately it's too big as a joint.
I will therefore have to wait until I have received the other o-rings to test the cap.

Yes if you spray paint the printed cap with a few coats it will be watertight. I do this on my endcaps all the time.

Ok Rob, i will use 100% infill.
i was wondering if i painted the cap, wouldn't that make the cap watertight ?

Hi,

I have a question for those who have printed endcaps for their wtc:
In the print settings, do you set the infill to 100%?
I find that by putting 100% the weight of the caps is high.

THANKS

indy1010,

I have always used 100% infill on my WTC end caps. It's my opinion that going with 100% will slow down any water penetration (if there is any!) I have run water tests to see how long it takes for water to penetrate at different infill settings. I found 100% is for sure the best. With that being said I still coat the inside of my caps with a two part resin to add that extra seal against water penetration.

indy1010,

Nice job! I really like the looks of the Typhoon. Keep us posted on well it does on the sea trials!

Hi,

it will not have bow thrusters.
I'm not a fan of wheathering and I have to say that painting was a difficult step for me, it's not my favorite thing.
can someone tell me what these white lines parallel to the water are for ?

[JHapprich]

Well done! Are you going to apply wheathering as well? Will it have bow thrusters, too?

...and with his painting.
It still lacks the markings and the matte protective varnish.
In reality the red paint is not as clear as in the photos. I used the same brand and reference as Bob in his video(Liquitex Professional Spray Paint - 12oz/400ml, Cadmium Red Medium Hue ref 0151):

Modification of one of the wtc supports which is smaller than the others (I don't know why).
