A question came to mind after looking at the pics again.

Why no impingement slot in the plexi top? With the tooling you have use of this should be no problem at all, and would be doable in one layer.

Cut the slit into the underside first, then mill down about 1/4 - 5/16" deep to allow for installing the inlet. A 1/4" - 5/16" deep opening isn't much for threads in acrylic. But more than enough to allow you to use epoxy for installation of a short 1/2" copper tube for inlet. And copper tube will be lower resistence compared to any barbed type fittings, can only help.

A top of this sort should help both the channel & tapered pin blocks.
