# Good Enough 4u0 — COTS Anchor Standard
|
|
|
|
**File:** `good-enough-4u0-cots-anchor-standard.md`
|
|
|
|
## Purpose
|
|
Ensure every design has at least one **Anchor COTS** part: a globally common, indefinitely available component that stabilizes the design and makes replication realistic.
|
|
|
|
## Anchor Criteria
|
|
- **Plentiful:** Mass-produced at global scale; no single-supplier risk.
|
|
- **Future-proof:** Likely to remain in production for decades (building trades, agriculture, logistics).
|
|
- **Local availability:** Stocked in hardware stores, farm suppliers, big-box retailers.
|
|
- **Interchangeable:** Accepts substitutes (different brand, slight dimension variations).
|
|
- **Non-exotic:** No boutique, hobbyist-only, or import-only parts.
|
|
|
|
## Example Anchors
|
|
- PVC pipe / EMT conduit.
|
|
- Mosquito screen.
|
|
- Hardware cloth / wire mesh.
|
|
- Zip ties.
|
|
- Pallet straps.
|
|
- Common bolts/nuts/washers (M6 / 1/4″).
|
|
|
|
## Documentation Requirements
|
|
- **Anchor Identification:** “This design anchors on 1/2″ EMT conduit.”
|
|
- **Substitution Map:** “Can also use 1/2″ PVC, bamboo pole, or hardwood dowel.”
|
|
- **Failure Note:** Explain what changes if a weaker/stronger substitute is used.
