Received loan of Teledyne RD Instruments Explorer OEM version. (without the enclosure)
Simple version
Goal of this version is to reduce manufacturing costs but limiting the number of setups and operations required to produce the final part.

Bottom Detailed view of DVL bore hole:
Widest standard I'D for o rings is 25.94
The dimension for the groove is slightly larger than the inner diameter of the o ring
Suggested stretch 25.94 + (25.94 * 0.05) = 27.237
Needed stretch 7.5%
25.94 + (25.94 * 0.0753) = 27.893282
Note I did the previous calculation wrong, I got the inner circumference of the o-ring, I did not divide by PI for the diameter. This seems to be a more reasonable size
There are quite a few options of o-ring diameters which inner diameters are compatible with the more reasonable sizing.
Alternate Version
Objective of this version would be to approach the DVL enclosure design with existing hardware. Additionally designing with live turning in mind to explore if there was an easier to manufacture approach than a deep trough enclosure design.

Laying Out DVL potential placements
The size of the existing dvl enclosure at the bottom of the sub.
Side view/ Note the enclosure can be moved slightly back to enable an unobscured view from the bottom facing camera
Proposed packaging with the battery tubes close to the main enclosure to interface with the downward facing DVL enclosure. Note, would need to rework the enclosure clamping system
Second option of placing the batteries below the dvl enclosure. Note the batteries is lower down on the sub which would lead to a more stable sub.
Views of custom DVL enclosure with batteries. Significantly less total volume needed to package within the sub enclosure.
Alternate design mounted. Note this is a very large design that would require a redesign of the frame and mounting additional ballast to counteract the volume of water displaced with this design.
