# How to make a cable slack-loop tray with vibe CAD

Collect excess cable in a broad open tray using the actual relaxed loop shape, rather than winding every cable around the same small post.

## Make this project
An unprinted organizer for loose cable at rest; no strain-relief, bend-life or electrical-protection claim is made.

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 the available desk area and the amount of cable slack to organize.
- Measure a relaxed loop that follows the cable maker’s guidance where available.
- Record jacket diameter and the largest connector that must enter or leave the tray.
- Choose entry locations from the real cable route with equipment disconnected.

## 2. Give your CAD agent this prompt

Create an open slack tray using loop_width, loop_depth, cable_diameter, connector_width, rim_height and entry_positions. Derive the inner path from the measured relaxed loop, not an arbitrary bend radius. Ask for missing cable-routing guidance and connector dimensions. Add broad openings instead of tight retaining clips.

## 3. Model and inspect
1. **Trace the relaxed loop** — Lay the disconnected cable naturally on paper and trace its outer and inner paths. Use that outline to establish the tray footprint.

2. **Create shallow guides** — Build a flat floor with low perimeter walls and optional wide interior guides. Leave sufficient space to lift the whole loop out without pulling a connector.

3. **Open the entry paths** — Cut two broad routing openings at the measured entry locations. Round their edges and keep their geometry independent of the outer tray footprint.

## 4. Check the prototype
- Compare the CAD path with the traced cable loop and verify that no guide forces a tighter turn.
- Move a connector-sized paper rectangle through each opening to check the removal path.
- Inspect the floor and wall sections for hidden closed cavities or narrow slots that would trap the cable.

## Avoid this mistake
Designing around cable diameter alone ignores the much larger connectors and the cable’s preferred resting curve.

## Choose the material
PLA or PETG may be considered for the tray. Sample the guide edges and fit; neither material establishes an acceptable cable bend radius.

### 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.
