Ok, amazingly, it cleaned up pretty nice.
This is the worst corner by far. I filled, this is rough sanded, still probably going to hit with filler again then final sand.
Overall view.
There's a small warp in the bottom piece, you can see the gap (though I think the desk is kind of warped too so it accentuates it), due to how I had it clamped overnight. The acrylic is going to slide in through a slot on the left side. Will be staining this starting later today. It's almost exactly the proper width for 7 slabs, there's about a 1/8" gap with them butted against each other. I'm pretty happy and considering this one a "save" after how poorly it was fitting yesterday.
