# How to make a camera eyecup storage case with vibe CAD

Store a detached spare eyecup without compressing its flexible rim. A small loose-fitting box provides a shaped recess around the rigid body and leaves the soft portion clear, with a sliding lid that avoids the accessory's attachment tabs.

## Make this project
An unprinted storage case for a detached spare, without camera-compatibility or protection certification.

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
- Eyecup outer width, height and depth in its relaxed shape.
- Rigid body dimensions and projecting attachment tabs.
- Clearance needed around the flexible rim.
- Available storage compartment and lid-removal space.

## 2. Give your CAD agent this prompt

Design a detached-eyecup storage case with body_width, body_height, rim_envelope, tab_relief, pocket_clearance, lid_thickness and lid_clearance. Ask for missing measurements and which surfaces are flexible. Locate the rigid body in a shallow recess while leaving the soft rim untouched. Add a loose sliding lid and rail coupon. Do not reproduce the camera attachment or claim impact or dust sealing.

## 3. Model and inspect
1. **Separate rigid and flexible outlines** — Measure the eyecup in its relaxed state. Draw the rigid mounting body and the flexible rim as separate references so the recess touches only the intended region.

2. **Build the recess** — Create a broad shallow pocket with relief around attachment tabs. Add a finger opening that reaches the rigid body without pulling on the soft rim.

3. **Add lid clearance** — Place the lid above the tallest relaxed feature. Review its sliding path and leave enough space beside the case for complete removal.

## 4. Check the prototype
- Inspect section views for clearance around the entire flexible rim.
- Review the lid-rail coupon before choosing its fit.
- Compare the pocket with a full-size outline of the detached accessory.

## Avoid this mistake
Measuring an eyecup while squeezing it can produce a recess that permanently holds the soft rim in a distorted position.

## Choose the material
PLA or PETG can be considered for the shell. Keep the accessory clear of rough interior surfaces during evaluation.

Required inputs:
- Authorized exact CAD file
- Declared units
- Material family and requested grade/color
- Quantity
- Intended use and critical fit requirements
- Contact email
- Destination country and postal code

**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.
