Dell OptiPlex 7000 / 7010 Micro - Snap-in P-Touch Label Plate

Dell OptiPlex 7000 / 7010 Micro – Snap-in P-Touch Label Plate (v18)

3D-printed plate that snaps securely into the diagonal vent slats on the front of the Dell OptiPlex 7000 and 7010 Micro chassis (same form factor). Perfect for asset tags, cable labels, system information, or inventory labels using standard Brother P-Touch tape.

The plate sits cleanly on the top edge strip above the power button and uses two custom parallelogram clip arms that match the 60° slat geometry.

Why This Design?
- Parallelogram clip arms (not simple rotated rectangles) so the arms sit flat against the slat walls instead of digging in at the corners.
- Triangular barbs with a moderate ramp angle (~32°) for easy insertion but good retention.
- Reinforced fillet at the arm base to prevent cracking during insertion (a common failure point in earlier versions).
- Press-fit / light snap behavior — the catch face sits just short of the full slat depth for a secure but non-destructive fit.
- Fully parametric Python source included so you can easily adjust dimensions or regenerate for future chassis changes.

Compatibility
- Dell OptiPlex 7000 Micro
- Dell OptiPlex 7010 Micro (identical chassis)
- Mount location: Top edge strip above the power button (uses the diagonal //// vents)

Print Settings (Recommended)

Setting Recommendation
| Orientation | Front face down (STL is pre-oriented) |
| Material | PLA (PETG also works but is more flexible) |
| Layer height | 0.2 mm |
| Walls/Perimeters | 3–4 (more = stronger arms) |
| Infill | 25% gyroid or grid |
| Supports | None |
| Brim | 5 mm |
| Print speed | Slow down at arm transition layers (z ≈ 2 mm) for better layer adhesion |

Test fit tip: Print the included "No Barbs" version first if you want to check fit without any risk of breaking barbs.

Installation
1. Align the two clip arms with a pair of diagonal vent slats above the power button.
2. Gently push the plate in until the barbs engage.
3. The plate should sit flush and level on the top edge of the chassis.

The design is intentionally a press-fit with light snap rather than an aggressive snap-fit to reduce stress on the arms.

Version History (Summary)
v18 (current) — Short, stocky design with BARB_H = 1.40 mm and CLIP_ARM_L = 5.75 mm. Refined press-fit behavior.

Earlier versions progressively improved:
- Arm shape (switched to true parallelograms in v9)
- Base reinforcement (fillet added in v10)
- Clip spacing and barb geometry tuning
