I have designed & arranged manufacture of an electronics enclosure for Titanium 160mm OD 130mm ID x 400mm Electronics enclosure that suits Blue Robotics RAILS internal brackets etc.
It is set up for up to 7 SubConn connectors including fibre optic to surface.
In GR2 Titanium design depth is over 2000m and in GR5 it’s 6000m.
Pricing is very attractive compared to commercial options for enclosures rated at over 1000m.
