# Good Enough 4u0 — Material Passport
|
|
|
|
**File:** `good-enough-4u0-material-passport.md`
|
|
|
|
## Purpose
|
|
A Material Passport documents any **non-standard** or **salvaged** material used in a design. It ensures clarity, replicability, and safe substitution.
|
|
|
|
## Passport Template
|
|
|
|
**1. Material Name**
|
|
- Common description (e.g., “Plywood offcut, ~12 mm”).
|
|
|
|
**2. Source Type**
|
|
- ☐ Opportunistic Salvage (one-time)
|
|
- ☐ Perennial Secondary Market (garage sale, thrift, flea)
|
|
- ☐ Industrial Junk Stream
|
|
- ☐ Other: ________
|
|
|
|
**3. Physical Specs**
|
|
- Dimensions (thickness, length, width).
|
|
- Weight or density (if known).
|
|
- Any markings or grades visible.
|
|
|
|
**4. Substitute(s)**
|
|
- At least one equivalent standard material.
|
|
- Note what changes in performance if substituted.
|
|
|
|
**5. Known Limitations**
|
|
- Weaknesses, environmental limits.
|
|
|
|
**6. Hazards**
|
|
- Sharp edges, dust, treatments, coatings, residues.
|
|
|
|
**7. Visual Reference**
|
|
- Sketch or photo recommended.
|
|
|
|
**8. Declared Use in Design**
|
|
- Component/function it supports.
|
|
- Why it was chosen (cost, availability, strength, aesthetics).
|
|
|
|
## Rule of Thumb
|
|
- **No Passport = No Approval** for non-standard or salvaged materials.
