## Make this project
An unvalidated passive desk cradle, not an electrical enclosure or a claim of equipment protection or operating performance.

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 housing width, depth and height, including feet and rounded corners.
- Measure the largest plugs used in adjacent ports and their insertion paths.
- Locate every existing opening, indicator and control on the hub body.
- Choose the cradle gap with a small housing-profile sample rather than a forced fit.

## 2. Give your CAD agent this prompt

Create an open hub cradle with body_width, body_depth, body_height, corner_profile, port_keepouts, opening_keepouts and cradle_gap. Use two low side guides and an open front. Ask for missing port positions and cable exits. Do not cover existing openings or add a tight snap fit around the housing.

## 3. Model and inspect
1. **Map the complete hub** — Sketch the housing and project port, indicator and opening locations onto its faces. Add the real plug envelopes to the same assembly.

2. **Place the guiding surfaces** — Build a shallow base with guides only on clear housing areas. Leave controls visible and avoid extending walls into the cable insertion paths.

3. **Make the cradle removable** — Add broad finger access and round exposed corners. Keep the hub as a reference body so cradle edits cannot accidentally modify its measured envelope.

## 4. Check the prototype
- Use a paper footprint with disconnected plugs to check simultaneous access to adjacent ports.
- Inspect the CAD assembly from every face and confirm all measured housing openings remain unobstructed.
- Check exported dimensions and plan a short guide-profile sample before assuming the hub will sit correctly.

## Avoid this mistake
A cradle that fits the bare hub may obstruct wide plug housings; model connected accessories as separate keep-out envelopes.

## Choose the material
PLA or PETG may be explored for the cradle. Choose contact geometry and clearance through a sample; material choice does not validate use around powered electronics.

**No payment at submission.** Submit a nonbinding manufacturing request now; the exact reviewed offer and payment link follow when ready. Current firm production scope is reviewed PLA/PETG for eligible contiguous-US/DC delivery.

### 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.
