# How to make a travel watch-strap divider with vibe CAD

Separate spare detached watch straps in an existing travel case, giving buckles and spring-bar ends their own space without forcing the straps into a new curve.

## Make this project
An unprinted organizer for detached straps, not a protective watch case or a validated restraint for travel.

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 each detached strap’s relaxed length, width and thickness.
- Record buckle dimensions and the full width of any attached end hardware.
- Measure the existing case interior and the clearance beneath its closed lid.
- Choose compartment spacing from the straps’ natural resting shapes.

## 2. Give your CAD agent this prompt

Design a removable strap divider with strap_outlines, buckle_keepouts, end_hardware_widths, case_width, case_depth, lid_clearance and divider_height. Use open channels that follow the measured resting shape. Ask for strap dimensions and case geometry. Do not force a bend, grip spring bars or claim protective travel performance.

## 3. Model and inspect
1. **Trace the relaxed straps** — Lay each detached strap naturally on paper and include its buckle and end hardware. Use the trace rather than straightening a curved strap to fit a rectangle.

2. **Allocate separate channels** — Place the traced envelopes inside the case footprint and add low dividers between them. Reserve wider end regions where buckles or fittings require extra space.

3. **Keep removal straightforward** — Lower divider sections beside the strap bodies for finger access. Preserve the measured lid clearance and keep the insert removable from the existing case.

## 4. Check the prototype
- Try a cardboard divider with the actual straps and confirm they lie in their resting shapes without compression.
- Inspect the closed-case section for contact with buckles and projecting end hardware.
- Check the exported case footprint and plan a perimeter-fit sample before making the full insert.

## Avoid this mistake
The buckle can be much thicker than the strap body; ignoring it can make an otherwise shallow insert interfere with the case lid.

## Choose the material
PLA or PETG can be considered for the divider. Evaluate a sample contact surface with spare material; compatibility with leather, coatings and polished hardware is not established.

### 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.
