20230107 USB dimensions
Splicing is out of the question.
Standard usb connector dimensions
reference: here
Straight through usb cables will have less diameter than 90 degree cable.
0.796 in (20.217 mm) apart
10 mm apart
Width of the usb-c connector: 10mm = 0.393701in
Diameter of the cable: 2.46 mm = 0.09685039
Tests:
cut desired usb cable and submerge underwater, determine if cable needs to be insulated. Theory is that when cable is cut water will run freely through the cable through the connector and destroy the camera.
See if usb cable can fit through an M10 hole
Test out o ring fitment
0.67 inches ~ 17 mm for the size of the hole to interface with the product link
Optionally we could use a single cable grip connector here with a square cord grip to achieve waterproofing
For cable grips see on the SDSU robosub here cable grips were directly threaded into the hull
