I wonder,do you have a 3D or 2D CAD files of the Heavy Thruster Guards?
Does not have much to do right now, so I’m going to mill a new bluerov2 frame in 1/2 thickness.(white)
I have made some changes,the height of bluerov2 is extended about 60mm,you can have 3 battery tube below instead of 1. (Bluerov2 will be 313mm high instead of 253mm)
Then you don’t need the Payload Skid (the bluerov2 will be 145mm higher with Payload Skid)
