# How to make a lens hood travel nest with vibe CAD

Give a detached lens hood a defined place inside an existing case compartment. A low contour nest locates its outer rim while leaving petal tips, bayonet features and delicate interior surfaces free of pressure.

## Make this project
An unvalidated packing organizer for a detached hood, not a protective case or camera mount.

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
- Hood outside diameter at the intended resting rim.
- Maximum width and height across any petals.
- Projection of bayonet tabs or release features.
- Case-compartment footprint and closed height.

## 2. Give your CAD agent this prompt

Create a loose lens-hood storage nest with rim_diameter, rim_width, petal_envelope, tab_clearance, nest_depth and case_width. Ask for missing dimensions and a side-view outline. Use a low locating ring with finger cutouts and relief around all tabs. Show the detached hood as reference geometry. Avoid reproducing its lens attachment and do not promise impact protection or secure transport retention.

## 3. Model and inspect
1. **Identify the resting rim** — Choose a broad exterior rim rather than a petal tip or bayonet tab. Draw that contact region separately from the hood's full outer envelope.

2. **Build the locating nest** — Create a shallow ring around the chosen rim with loose clearance. Break the ring where fingers need access and where tabs project outward.

3. **Review the case envelope** — Add reference walls and a ceiling for the existing compartment. Check the hood's tallest petals and its lift-out path before adding any labels.

## 4. Check the prototype
- Compare a full-size ring outline with the detached hood.
- Review a short rim coupon before choosing final clearance.
- Inspect the closed-case reference for contact with petal tips.

## Avoid this mistake
Treating a petal hood as a simple cylinder can conceal the points that touch the case lid first.

## Choose the material
PLA is useful for dry shape exploration. PETG is another candidate; the design should remain loose rather than clamp the hood.

Required inputs:
- Authorized exact CAD file
- Declared units
- Material family and requested grade/color
- Quantity
- Intended use and critical fit requirements

**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.
