# How to make a doorstop storage cup with vibe CAD

Keep a loose wedge-style doorstop in one place when it is not being used. An open-top cup follows the wedge's thick end and includes a finger opening so the item lifts out without a tight fit.

## Make this project
An unvalidated holder for storage away from moving doors; no door-control function is intended.

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
- Doorstop length, width and maximum thickness.
- Angle or curved profile of the wedge.
- Available storage footprint away from the door swing.
- Space needed to grasp the thick end.

## 2. Give your CAD agent this prompt

Create a freestanding storage cup for a detached doorstop with stop_length, stop_width, stop_height, pocket_clearance, cup_depth and finger_opening. Ask for missing dimensions and storage orientation. Use a loose open pocket with a broad flat base. Keep part of the doorstop exposed for gripping. The printed object is storage only; do not model a replacement doorstop or a door-holding mechanism.

## 3. Model and inspect
1. **Choose the storage pose** — Place the doorstop on its side or flat face and decide which end remains exposed. Favor a low arrangement over a tall narrow cup.

2. **Make a reference wedge** — Model the measured outline as a separate reference body. Offset its sides to define the pocket without copying every surface texture.

3. **Open the gripping area** — Remove part of the front wall so fingers can reach the item. Round the remaining rim and review the base footprint for rocking.

## 4. Check the prototype
- Check a paper footprint in the proposed storage location.
- Inspect the pocket section to ensure the wedge cannot become trapped beneath a lip.
- Use a small pocket coupon if the doorstop has an unusual curved profile.

## Avoid this mistake
A pocket copied exactly from a textured rubber wedge can grip too tightly and make the cup lift with the doorstop.

## Choose the material
PLA or PETG can be considered for the holder. Select clearance through measurement and a coupon rather than material assumptions.

**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.
