Four mini PCs, a switch and an external drive hung under a desk in a single plywood box — cut from one sheet, clamped on with no holes drilled in the desktop. Two bays face opposite directions, so you see clean hardware from the chair and every cable is hidden behind it.
Both run in the browser. Drag to orbit, scroll to zoom, click any piece to isolate it.
Watch the eight pieces lift off the 4×8 sheet and assemble themselves. Every length dimensioned on the board, plus an exploded view.
The finished box under a desk, with clamps, equipment and the cable routes drawn in. Cross-section toggle shows the two opposite-facing bays.
Clear space is the air inside each bay, wood excluded. Both bays are identical.
One 4×8 sheet of ¾" PureBond birch (0.703" actual). All cuts are straight rectangles — no joinery of any kind. R1–R3 are the three rip cuts.
| # | Part | Length | Width | Qty | Rip | Holes |
|---|---|---|---|---|---|---|
| 1 | Top panel | 33" | 10" | 1 | R1 | — |
| 2 | Clamp doubler | 31-9/16" | 2-3/4" | 1 | R3 | — |
| 3 | Front wall | 31-9/16" | 3-15/16" | 1 | R3 | — |
| 4 | Middle shelf | 31-9/16" | 10" | 1 | R2 | 5 x 2" grommet holes, one per device |
| 5 | Side panel (left) | 10" | 8-9/16" | 2 | R2 | — |
| 6 | Rear wall | 31-9/16" | 3-15/16" | 1 | R3 | 6 x 2" cable pass-throughs, equally spaced |
| 7 | Bottom panel | 33" | 10" | 1 | R1 | 12 x 1-1/2" vent holes, 2 rows of 6 |
23 holes across three panels, two hole saws (1½" and 2"). Positions are measured from the left end of that piece.
| Panel | Count | Across the length | Position | Purpose |
|---|---|---|---|---|
| Middle shelf | 5 × 2" | 3-11/16" · 9-15/16" · 16-3/16" · 22-7/16" · 28-5/16" | 7-1/2" from front | cables up into the hidden cable bay |
| Bottom panel | 12 × 1½" | 3-1/4" · 8-1/2" · 13-3/4" · 19" · 24-1/4" · 29-1/2" | 2-1/2" and 5" | cool air in, two under every device |
| Rear wall | 6 × 2" | 2-5/8" · 7-7/8" · 13-3/16" · 18-7/16" · 23-11/16" · 28-15/16" | 2" up | cables straight back to the wall |
Drawings are print-ready on US Letter. Sheet 9 is written as a cut request you can hand to the panel-saw associate.
The front wall closes the upper bay and the rear wall closes the lower one. Because they sit on opposite faces, the cross-section forms a closed loop — that is what stops a 33"-wide box with no back panel and no front panel from racking into a parallelogram.
Each machine's cables go straight up through the grommet directly behind it, into the bay you cannot see, and out the open rear to the switch and power. Six more holes in the rear wall take anything heading straight to the wall.
Four heavy-duty C-clamps grip the rear edge of the desk, out of knee space and hidden against the wall. A doubler under the top panel gives the jaws 1.41" of plywood to bite so they cannot crush the top ply.
Every device sits over a pair of floor vents, has an open front, vents up through its own grommet and has a pass-through in the wall behind it. There is no sealed pocket anywhere in the box.
