This is great project
I would be interested in helping you with advice on producing a high quality production standard prototype, if you would be OK about using aluminium in various forms & finishes.

I have worked on optical systems for submarines in the past, so this is right up my street
Let me know if you’re interested
All the best

Hi @GaryTrafford, I'm really glad you like my article. Yes absolutely, I would love to hear your advice on pushing this project further. 3D printed parts have their limits so it would be great to explore the idea of using of aluminum! Let me know the best way to contact you and I will be in touch. Many thanks.

Inspiring project, perhaps one day I will make one.

Some suggestions that may be useful for the future.
From work with vacuum systems if a glass window sits on an O ring then as the external pressure increases the seal improves, so a perspex window sitting on a flange may be more robust (ignore me if you did that!).
For none pressurized 3D printed items I have found applying super glue over the external surface is absorbed between the print layers and makes the item very strong. I then spray coat with clear paint as used for sealing metallic paint, this is certainly waterproof in a none pressurised environment.
Finally I would add some silica gel packets close to window and camera. Every underwater camera I have used has suffered from lens misting once it gets cold. If you are lucky enough to have access to dry nitrogen gas you could purge the vessel before sealing it up.
Great project and I look forward to seeing the results.

Thanks @Boss, these are some great suggestions! You make a good point about the perspex window, I will be changing the design later to accommodate for higher pressures and I certainly think adding flanges and gaskets will be more effective than making custom O-rings. I didn't think to use super glue and sealing paint either, I will definitely have to give this a go. I have been collecting silica gel packets for this very purpose, when I make a more robust internal electronics chassis I will cable tie a few to the inside. Thanks again, great stuff!

@Ghostkingz Thank you. ^_^

Remember we were thinking of sending Pete Wood into space, well I have another idea.

@GreigRS I'm still up for that! :-)
