10 Stand v5: portrait, beside the main monitor

After v4.1 (9.4) the idea changed. I wanted the screen in portrait, beside my main monitor, so its height matches the main monitor's. The main monitor is an LG 49WQ95C ultrawide in landscape.
So v5 is a vertical unit on a desk stand, in the same Neo-Braun style as v4, with the PC in the base.
One wrong number
My brief said the screen's bottom edge should be level with the main monitor's, and I gave it as 75 mm above the desk. That was wrong. It's 175 mm. I corrected it the same day, but one wrong number in a brief moves the whole design.
This time I didn't ask ChatGPT for a reference picture. Claude designed it straight in FreeCAD.
The base
The base is as wide as the screen, 222 mm, so from the front the base and the screen read as one column. It's 55 mm tall and 200 mm deep.
- A floating front panel sits over a 1 mm shadow gap.
- A radial halftone over the PC's side vents is the intake: 135 holes.
- A second halftone in the top is the exhaust: 195 holes.
- The halftones are the only ornament.
The PC lies flat. Its front, with the power button, the USB-A ports and the jack, is at a window in the outer side. Its rear ports face a 50 mm plug bay.

The fin and the ballast
A 20 mm fin, printed flat, stands in a socket at the back. It leans forward about 18° to the screen.

Ballast comes from the parts drawer again, as in v4.1. Three trays hold loose M6 nuts and bolts. About 1.45 kg of it clears 5 N on every edge at every swivel angle.

Never printed
At the slice defaults v5 is 12 h 36 min and 490 g, plus the ballast. I never printed it. The next step went to the shelf instead (11).
What did survive is the swivel. It carried on unchanged into the shelf mount, and it's what's on my desk now.
- 10.1 The swivel: a friction bolt, an arc groove for the stops, and the checks.
- 10.2 Measuring the real desk: the desk, the oak shelf, its steel legs and the main monitor as a model.
