## Make this project
An unprinted storage organizer, not a hardware gauge or an assessment of a screw’s structural suitability.

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 longest screw including its head and the widest head diameter.
- Record the length groups and approximate quantity assigned to each bay.
- Measure the drawer interior and the clearance beneath the drawer above it.
- Choose pickup recesses using the actual screws and your usual handling method.

## 2. Give your CAD agent this prompt

Create a hardware sorter with screw_lengths, head_diameters, bay_quantities, drawer_width, drawer_depth, tray_height and label_width. Use shallow open bays and a continuous floor. Ask how screw length is being recorded and request the actual drawer dimensions. Do not infer thread type or hardware suitability from a storage label.

## 3. Model and inspect
1. **Define consistent labels** — Decide whether the recorded length includes the head and use that convention throughout the tray. Separate visually similar head styles before assigning bays.

2. **Size the compartments** — Allocate longer bays to long screws and wider bays to larger quantities. Leave room beside the hardware for fingers or the intended pickup tool.

3. **Add access and identification** — Create front label recesses and broad corner transitions. Keep labels outside the hardware space and preserve uninterrupted walls between neighboring length groups.

## 4. Check the prototype
- Arrange representative screws on a paper layout and confirm the longest item lies entirely within its bay.
- Inspect the tray section against drawer height with the largest screw head included.
- Check the exported bay labels and dimensions; request a corner sample if pickup access or finish remains uncertain.

## Avoid this mistake
Mixing head-inclusive and under-head measurements can put different screws under the same label; choose one documented convention per group.

## Choose the material
PLA or PETG can be considered for the tray. Sample the floor and corner finish with spare hardware; material choice does not establish wear or load capacity.

**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.
