Mini Underwater ROV v2

The above is the second design for a miniature underwater rov. The main picture and MiniROV_v2_full_model.stl file shows it all put together with the small project enclosure and the 1/2 inch PVC pipes. The motor mounts were designed to hold small dc hobby motors which would then be sealed in some sort of resin.

This design is still a work in progress and is one of my first using OpenSCAD. Please comment below. Advice is always appreciated.
