Its definatly not a WW killer, but I'm happy with the design. Its hard to say one design is better than another, the WW fulfills its design requirements wonderfully, but my requirements were different. For a start it had to be less that 45mmx45mm to fit on GFX cards.
Base was made on a lathe, then drilled and tapped holes in each corner. Middle plate was manually milled for the slots, then drilled in each corner again. Top is drilled, tapped holes with a lathed o-ring groove ( not pictured )

Don't actually need to, and probably couldn't anyway. The base is VERY thin, and the lathing process leaves a slightly round surface are the bottom of each channel anyway. ( slight ridges, about 0.1-0.2mm high and wide, perdendicular to the channel walls, the ridges are about 0.5mm appart. I nice little side effect in my opinion.
@Kwissus
Sealed with an o-ring on the base and one on the top plate. The machinist forgot to put an o-ring groove on the top plate this time, but its only a prototype, so I'm not that bothered, I'm just going to make a gasket from silicone sealant, and clamp down on that with the socket screws.
