I think this is the last one, if I could just stop messing things up. The only real change is the added semi-circular bump on the lid, and a matching channel (that should also be a semi-circle, but I messed up the gcode) on the bottom piece. The idea of those is to prevent torque from being applied to the hinge when the device is closed.
In the left-hand image, you can see the two halves separated. Both LOOK pretty good, though if you look carefully at the bottom (right piece), you can see that it's somewhat out of round- the right edge is thicker than the left. That's my fault for not setting up a good reference when flipping the piece over. SIgh.
The right image shows this asymmetry. The lid doesn't sit in the right spot, leaving a lip that's definitely big enough to be obnoxious. If you look carefully, you can also see that the lid has a terrible bevel, and is chewed up a little bit. That's another user error... I cut the inside of the lid first, contrary to my own in-code directions, so I couldn't chamfer the edge. I tried to do that manually on the lathe, and it didn't work so well.
There are a couple other things that needed manual rework, mostly the hinge. I need to have the gcode round off the male part, and make sure the female part gets cut all the way out. On these pieces, I had to do that manually with a file.
So: Remember to drill a reference hole for the bottom part, read the instructions for the top part, and it should be all good. I sure hope so, since I've got a LOT of these pieces floating around, all with various flaws.
