LCD panel mount to lightstand stud

Fellow Shark-o-files:
Here's the second fabricated part in a short run of three. At the local CNC club I'm in, we had need to mount an LCD screen (36+") high enough people could see during the meetings. Rather than construct some hoist, or pay for some ultra-strong purpose-built mount, I decided to try using my Manfrotto (brand) photographic light stands. Using AutoDesk Fusion360 to model the part, then BobCAD to do the toolpath generation. Then, from a 3.25" long piece of 2" square aluminum bar, comes this little beauty.
The first picture is from Fusion360, of the original design
The setup you see in this next picture is a KURT D688 machining vise attached to the Shark HD2+ bed, with two setup blocks, a set of parallels, and then a piece of aluminum specially cut to be the fixture for the part. The block of material starts out getting four holes underneath, which I tap using a TapMatic head on my drill press. Those four holes match the ones that go through 0.150"-tall bosses, so the block of material sits up off the fixture. That way I can get the bit all the way down the edge.
This final picture (since the system only allows three per post) is of the part in use. it's mounted on a standard photographic "stud", held on with that knob. The currently-unoccupied hole is threaded to 3/8NPT. That way, when the larger screen arrives, I can thread in a short pipe that I can then add counter-weight to offset the screen's desire to pull forward. So far so good!
Yes, if you look closely the front bore isn't centered. Thankfully that's not a problem with this particular design, but it sho'nuff looks odd .
Anyway, just a short fun project in Aluminum. Total machining time, given the fine detail done with a ball-nose end mill, wasn't so bad, a couple hours on the Shark HD2+ I have. More than adequate!
Cheers, y'all.....
