## Make this project
An unvalidated craft-bench rest for brush handles, not a protective container or a claim about paint compatibility.

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 handle diameters at the points that will touch the rest.
- Measure the longest bristle projection beyond those contact points.
- Record the desired number of brushes and spacing between loaded brush tips.
- Measure the liner footprint and choose saddle gaps through a small sample.

## 2. Give your CAD agent this prompt

Build a brush rest with handle_diameters, saddle_pitch, support_height, bristle_projection, liner_width and liner_depth. Support handles only and leave bristles clear of the body. Ask for brush sizes and the intended removable liner. Use open rounded saddles without claiming chemical resistance or a universal handle fit.

## 3. Model and inspect
1. **Place the bristle envelope** — Draw the brushes in side view using the actual support points. Reserve an open region below and beyond the bristles for the liner.

2. **Build the handle saddles** — Create two low rails with broad rounded notches at matching positions. Keep the spacing adjustable so different handle tapers can be accommodated.

3. **Make cleanup accessible** — Keep the rest open beneath the bristle area and avoid hidden paint-catching cavities. Add a separate liner outline as a reference, not as a supplied accessory.

## 4. Check the prototype
- Use a cardboard side profile with clean brushes to check handle contact and bristle clearance.
- Inspect the top view for brush-tip overlap when every saddle is occupied.
- Plan a saddle sample and check it with the real handles before deciding the final notch gaps.

## Avoid this mistake
Measuring only the ferrule ignores handle taper and bristle length; locate the actual contact points before setting support height.

## Choose the material
PLA or PETG may be considered for the rest. Use a removable liner and check the paint maker’s cleanup guidance; chemical resistance is not established by this recipe.

**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.
