## Make this project
This unprinted geometry guide is for an unpowered prototype; it provides no electrical insulation, shielding or cable protection rating.

This recipe has not been physically validated. Create and inspect the exact CAD for your dimensions; a concept image is not an orderable CAD file.

## 1. Measure
- Measure ribbon width and thickness without flattening folds or pressing the conductors.
- Measure both connector housings and their insertion and removal directions.
- Record the straight routing distance and any existing folds that must remain unforced.
- Choose lateral clearance from a sample using the actual disconnected ribbon.

## 2. Give your CAD agent this prompt

Create an open ribbon tray with ribbon_width, ribbon_thickness, route_length, side_gap, wall_height and connector_keepouts. Model only a straight route unless measured routing guidance is provided. Ask for connector envelopes and existing fold locations. Do not add clamps, sharp turns or a cover that presses onto the ribbon.

## 3. Model and inspect
1. **Draw the routing centerline** — Place the disconnected ribbon and connectors on paper to establish the straight section. Stop the tray before connector manipulation space begins.

2. **Build low side guides** — Extrude a flat base and two shallow walls. Keep the top entirely open and make side_gap an explicit parameter for revision.

3. **Open the ends** — Round each tray entrance and remove any end wall. Add optional alignment marks outside the ribbon path so they cannot catch its edges.

## 4. Check the prototype
- Overlay the ribbon and connector outline on the CAD plan and verify the tray stops outside both removal paths.
- Inspect cross sections for uninterrupted clearance and confirm no decorative feature enters the ribbon space.
- Plan a short tray coupon to assess fit and edge finish while the prototype remains disconnected.

## Avoid this mistake
The connector removal envelope is often wider than the ribbon; extending guide walls too far can obstruct unplugging.

## Choose the material
PLA or PETG may be explored for the passive tray. Use a measured sample fit and smooth contact geometry rather than assuming a material protects ribbon conductors.

### Agent submission steps
1. **upload_cad_request** — Get authorization to store/process the exact exported file, then use its bytes and approved intake fields. Save the returned request ID and file SHA-256.

2. **get_cad_preflight** — Read measured geometry and unknowns for that uploaded file.

3. **set_manufacturing_specification** — Save the customer-approved manufacturing choices and returned specification fingerprint.

4. **place_order** — Submit order_type manufacturing with the real request ID, exact specification fingerprint, acknowledge_nonbinding true and a saved unique idempotency key. Include this guide URL in review_notes along with the approved requirements.

5. **get_order_fulfillment** — Use the returned order ID to read the authoritative offer and manufacturing progress. A recipe URL alone never identifies an order.

Reconcile an uncertain result before retrying. Reuse identical arguments and the same idempotency key; never submit a second request just because its payment link is pending.
