"""
The Stop Bar: the Tapper moved onto a longer bar that stands on two feet,
with a stop button in a yellow box at one end and the electronics in a small
project box. The board, the relay and the fuse are inside the project box, so
only the box shows, with the test button on its lid.

Run from the cad/ folder:

    uv run stop-bar/model.py

It writes, for the site:
    site/public/files/stop-bar/stop-bar.step    the whole assembly, for editing
    site/public/files/stop-bar/stop-bar.glb     the 3D model shown on the page
    site/public/files/stop-bar/stop-bar-cad.py  this script, and console.py beside it
    site/src/content/instruments/stop-bar/drawings/stop-bar-render.svg

It builds the Tapper with the Tapper's own script (cad/tapper/model.py). Every
part is bought, so there is nothing to print. The parts are drawn only well
enough to show where they go. Coordinates in millimeters: X along the bar, Y
across it, Z up from the bench.
