I used to be involved in oceanographic research early in my career. I was a tech back then so my job was ensuring hydrophone arrays and equipment was sealed for the depths. One thing we did was fill array tubes with mineral oil. It’s nonconductive and doesn’t shrink under pressure. It was really good, just seal the ends and it kept water intrusion to nil. Also when we had anything that had a motor it prevented it from shorting out as well.
Crazy amounts of underextrusion in the overall surface finish of that part at 4:15. Even if it passes the initial short term water leak test, long term you're going to get water gradually wicking its way through the plastic over time. If you want to persist with 3d printing parts for projects like this, the printer will serve you better by printing a negative mold that you can pour resin into or another similar material that won't absorb liquids as much.
Great series, loved watching this, but I have a question: after he makes sure it's water tight, he makes a hole for the bearing/motor shaft and two other holes. How do these openings not allow water to leak in?
@@anthonyortiz7924 It was filled using a syringe, and if the grease is replenished frequently, the leak can be prevented. (Actually, I use Vaseline by melting it with a hot gun.)
@@tiver21 ahhh I see, I figured it must be a temporary solution and require replenishment. Thanks for replying, this series was so interesting to watch as someone who is just starting to look into RC.

When making a waterproof servo, fill the inside with oil. As you said, it worked well.
thank you
절대적으로 환상적입니다. 나는 오랫동안 이와 같은 것을 만들고 싶었지만 작업에 대해서는 거의 알지 못했습니다. 공유해 주셔서 감사합니다. 그런 위대한 솜씨. 안녕하세요 독일에있는 영국인에서 한국에 :)
The mouse pad though 😂🤣
my wrist is comfortable
@@tiver21 Its living the dream🤣

Very interesting, thx!
Lathe and plexiglass to help. I sharpened myself on the machine
Try looking for cup-style oil seal for your prop shaft in motorcycle shops. They come in 4mm ID.
They do but I wonder if this motor has enough torque to let that work.

It is waterproof by filling the inside with grease.
@@tiver21 filling the inside of what with grease, the holes around the shafts? Doesn’t water eventually push its way in?

Another interesting project👍 How you make the metal ball bearing water tight or there are? Which material is the tube Acrylic? Take care!
i think those compartments are usually done in acrylic.
Where do you get O-Rings , I only find 3mm diameter
Welcome to the party.
Do you have stl file end cup WTC 90 mm
That 3D printer defo needs some work
Pepe!!!😂
what that
Don’t use that kind of jelly on gaskets.
