# How to make a desktop bookmark rack with vibe CAD

Separate flat bookmarks in a compact row of slots so the one you want can be lifted without untangling tassels or bending neighboring pieces.

## Make this project
An unvalidated organizer for bookmarks on a desk, not a book support or a clamp for valuable paper items.

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 widest and thickest bookmark, including any laminated edge or attached clip.
- Record the number of bookmarks and the maximum tassel or ribbon length.
- Choose a visible height above the rack so individual designs remain recognizable.
- Determine slot spacing with a folded-paper mockup that includes your fingers.

## 2. Give your CAD agent this prompt

Create a bookmark rack with bookmark_width, bookmark_thickness, slot_count, slot_pitch, slot_depth, rack_length and tassel_gap. Use separate vertical slots with an open top and rounded entrances. Ask whether the bookmarks have clips or tassels and request missing dimensions. Leave slot_clearance as a measured or coupon-selected parameter.

## 3. Model and inspect
1. **Organize the slot pattern** — Lay out the intended bookmark count along the desk edge. Reserve extra space beside any bookmark with a bulky clip rather than forcing equal gaps.

2. **Build the shared base** — Create a low continuous base and add separators as individual features. Stop separators below the visible artwork area and leave the rear open for ribbons.

3. **Make entries readable** — Round slot entrances and add optional shallow numbered marks to the front. Keep marks separate from slot walls so they do not reduce insertion space.

## 4. Check the prototype
- Arrange actual bookmarks over a paper plan and confirm fingers can reach each position without moving its neighbor.
- Inspect the smallest slot in section and check that a clip or laminated seam cannot bottom out unexpectedly.
- Verify the exported pattern count and outer length, then plan one representative slot as a fit sample.

## Avoid this mistake
Treating every bookmark as a plain rectangle misses clips and tassels; include those protrusions in the insertion path.

## Choose the material
PLA or PETG can be explored for the rack. Check a sample entrance for roughness and adjust the geometry before placing delicate bookmarks in it.

Have the model ready? Upload the exact customer-approved file. Starting from this guide? Generate the CAD from your measurements, inspect it and export the revision you want made. Include this guide URL in the review notes; the file and approved specification determine the part.

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.
