Working on the recovery tank design as time allows. Never owned or used a clear cover, so I'm just winging it. Definitely more difficult to use a fixed tank size, and make the window as large as possible.
Tolerances are tight. O-ring will be approximately 2.0mm. O-ring is approximately 2mm from the hole, and 2mm from the M4 screw threads.

Will need help with the CAD drawing, then can maybe 3D print a simple flat with just the O-ring groove. Need to find an appropriate size o-ring, or use cord stock.
The following area in yellow shows the size of the bezel. Left 5mm around the perimeter for the welding bead. I think the lexan should be slightly recessed into the bezel, to put the right amount of pressure on the o-ring when the bezel is fully tightened down.
