# How to make a desk grommet cable divider with vibe CAD

Organize an existing desk pass-through with a removable divider insert whose openings accommodate the actual connectors and leave the desk hole usable.

## Make this project
An unprinted desk-opening organizer, not a desk reinforcement, cable restraint or replacement for an electrical fitting.

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 grommet opening in two directions and its usable internal depth.
- Record any taper, rim or removable cap that the insert must clear.
- Measure the largest connector in each cable group and its passage direction.
- Choose an easily removable outer gap using a paper or cardboard insert.

## 2. Give your CAD agent this prompt

Model a removable grommet divider with opening_width, opening_depth, insert_height, rim_keepout, divider_positions and outer_gap. Use open compartments large enough for the supplied connector envelopes. Ask for the opening shape and cap clearance. Avoid a press fit, desk fasteners or any feature that grips the cable jacket.

## 3. Model and inspect
1. **Map the desk opening** — Sketch the measured opening and its cap or rim keep-out. Set insert depth so the divider remains accessible from the top.

2. **Allocate connector passages** — Place the largest connector envelope in each compartment before adding divider walls. Leave a continuous withdrawal path rather than sizing only for cable diameter.

3. **Add a removal tab** — Create a small accessible finger tab outside the cable paths. Round upper edges and keep the insert as one distinct removable body.

## 4. Check the prototype
- Try a cardboard layout in the actual grommet without forcing it and check that the existing cap still moves freely.
- Trace each connector’s route through the CAD compartments, including diagonal orientation if that is required.
- Verify the export’s outer dimensions and plan a perimeter-fit sample before requesting the complete insert.

## Avoid this mistake
Dividers sized around connected cables can become impossible to remove after a connector is unplugged and needs to pass through.

## Choose the material
PLA or PETG may be considered for a removable insert. Validate the edge finish and outer gap on a sample; do not force a mismatched fit.

### 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.
