Starting my build of my ROV that is based around the BR 4" Tube. I am using the rounded front end with the 14 hole tail. Will be powered by pixhawk/ardusub, with RPI camera. The frame itself mostly PVC pipe based, with a few bits of acrylic here and there.
Here are some files I have created so far for my sub:
Updated both designs. The internal plate can now be removed while the flanges are still installed (a bit of lost mounting room, but I think ill be ok).
The tube holder design now has a rounded top (originally I was going to use a flat plate above and below the tube)…
