Hi Guys,

I am planning to make a Amethyst AUV Platform (https://beobachtung3d.com/) this summer.

This should be the final result:

Here are the pieces I have printed so far...
I already want to ask you something... Do you think a plexiglass pipe with the two caps 3D printed is a good idea (the DIY way) or is it better to buy an already made and tested enclosure? The enclosure I have found and that seems really good is by blue robotics (this one: https://bluerobotics.com/store/watertig ... e3-asm-r1/) what do you think? Have you had experience with their products? Do you know better companys maybe in europe (I live in Italy).

Thankyou for all the help and hope this project will be a fun one

In the quick tests I did 3D printed caps (even printed at 100% infill) will not be waterproof at depth. I would go with a ready made enclosure like you linked especially if you have some money wrapped up in the electronics.

Thankyou. Yes thats my same thought. Just to go cheap but having it breaking up its not worth it. I will buy from blue robotics then.

Afterwards I will try less important modules in the diy method.

But I agree with you, the central part should be safe.

Reminds me of this...

here is the progress.

So you all advise me to buy blue robotics 3'' series enclosure? I live in europe so the shipping will cost me...

This is the kit I am thing to buy. Maybe the cylinder a bit shorter. https://bluerobotics.com/store/watertig ... e3-asm-r1/

Buenas noches.

Si esa sería la mejor solución, pero si vives en Europa, te aconsejo que mires en Aliexpres, tienes el mismo tubo, con una de las tapas del extremo del domo curvada, por bastante menos dinero.
Comprueba que las medidas sirvan para tu proyecto.
Un saludo.


Good night.

If that would be the best solution, but if you live in Europe, I advise you to look at Aliexpres, you have the same tube, with one of the caps at the end of the curved dome, for considerably less money.
Make sure the measurements work for your project.
Greetings.

BlueRobotics team was amazing! Super fast shipping!

They also included silicon grease the little blue stick and a sticker!

This is the 3'' version.

From what i hear, BR is quality materials. They've done their research. Hope it works out for you!

They seem really high quality pieces.

Its a shame that living in europe I had to pay 30€ just for shipping and now I will also pay the customs duty and IVA which I just recieved and It's really high .

At least I hope it will work great and will allow me to go deep


Heres a little update:

I made the 3D model of the front part. It has a detachable front so that I can insert a camera lens in it if i need or a probe such as a current flow probe.
Any thoughts?



UPDATE... Here are the 3dmodels (STL):

Beautiful shape, only I think that the watertightness leaves something to desire. I think that you can achieve a better succes with swaping the whole dome if required. Because a flat surface is "easy" to make waterproof.
