# Sag-Mesh Plane v0.1 — Certificate of Central Compromise (CCC)
**File:** `sag-mesh-plane-certificate-central-compromise.md`
**1. Design Name**
Sag-Mesh Plane v0.1
**2. Central Compromise**
The plane is formed from a deliberately under-spec PLA+ mesh grid printed only in the Y-axis, with large spacing (23 mm) that sags and barely fuses. Flatness and stiffness come from filling this flawed mesh with cheap cement/plaster.
**3. Purpose of Compromise**
To create a rigid, flat panel at extremely low cost by combining a weak, flawed printed lattice with abundant, globally available fill material.
**4. Good-Enough Justification**
The cement provides bulk stiffness; the mesh provides shape control. The result is good enough for jig boards, shelf shims, or tool bases. Not structural, not outdoor-rated—but usable, cheap, and replicable anywhere.
**5. Replicability Proof**
Anchor COTS: rapid-set cement mortar (globally ubiquitous).
Alternate: Plaster of Paris or Perfect Cast for lighter builds.
**6. Substitution Map (Optional)**
- Heavier/stronger: Portland cement.
- Lighter/weaker: Perfect Cast plaster.
- Optional: mosquito net as a poor-mans fiber mesh insert.
**7. Failure Envelope**
- Not for load-bearing or structural use.
- Fails by visible cracking or edge chipping.
- PLA creeps under heat; not to be left in hot sun or car.
**8. Statement of Intent**
This design embraces flawed printing and cheap fill to democratize stiff panels, trading durability and precision for cost, ubiquity, and accessibility.
