# Visual BOM Brief — Tunable Snare Frame Array

## Render Brief for Visual BOM

Generate an exploded-view diagram or isometric parts layout showing the main components of one drum unit (Shell B, 8-inch) as representative:

1. **Steel shell cylinder** (203mm OD × 50mm, 1.0mm CRS) — show as a rolled cylinder with visible TIG seam and 45° chamfer on top rim. Silver brushed steel finish.
2. **Remo Ambassador drum head** — white/translucent Mylar circle, larger than shell OD (head rim overhangs by ~5mm per side). Show seated on shell.
3. **Counter-hoop** — thin steel ring, same diameter as head, shown floating above head before tensioning.
4. **Tension rods** (6×) — short threaded rods with hooked ends, shown arrayed around hoop-to-lug positions.
5. **Lugs** (6×) — small claw brackets welded to shell exterior. Show at each tension rod position.
6. **Snare mechanism** — small bracket at 6 o'clock with thumb-wheel, snare wires running across head underside.
7. **Mounting frame** (partial) — show one section of the flat bracket with the 205mm circular cut-out that Shell B drops into.

**Color palette**: silver steel for all metal; white/translucent for drum head; black for lug hardware; accent the frame in a slightly darker steel tone.

**Use for**: `images/visual-bom-shell-b.png` (placeholder image slot in explorer.html)
