FIELD GUIDE / 09

Design and publish cases & accessories with AI

Use the official STL with Codex and Blender, then let AI submit your printable design for review.

Before you start: connect Blender

Install Blender and follow the project documentation to connect Blender MCP to Codex. Keep Blender open and confirm Codex can read the scene before designing.

Blender MCP setup documentation ↗

Verify the environment and copy the creation prompt

Complete the setup above and verify Codex can read the scene through Blender MCP before copying the complete creation prompt below.

DESIGN WITH AI

Describe your idea. Design it with AI.

A replacement shell, protective case, stand, or another idea. Copy the prompt, use your configured Blender MCP connection in Codex, and describe what you want.

Describe your idea, then copy the complete prompt

First read the current scene through Blender MCP. If disconnected, help me complete environment setup before continuing. Download the official AI Passport reference:

Dimensions and notes: https://ai-passport.folotoy.cn/assets/models/ai-passport-reference/2026-09-14/manifest.json

I want to design (required)

Extract the ZIP and import the STL, interpreting coordinates as millimeters (STL does not encode units); check its overall bounds are approximately 61 × 96 × 8.32 mm. Build and iterate on my idea. Ask for missing internal geometry or mounting dimensions; do not guess.
Use AI Passport only for dimensional reference and fit checks. Export only my designed parts, excluding the reference from print files, source, previews and cover.
Design for 3D printing: closed solids, suitable walls and clearance, minimal overhangs/supports, split into assemblable parts when needed. Export each part as millimeter STL/basic 3MF. Save an editable source containing only my parts, a portrait 3:4 rendered cover and printing/assembly notes. State honestly when no print or fit test was performed. I will paste the official upload prompt when ready to submit for review.

Tip
Keep Blender and its connection running. The prompt includes the STL download; extract it and import using millimeters.

Describe and refine your idea

For example: a desktop stand with rounded edges. You can also design a replacement shell, protective sleeve or another accessory. Inspect the model and ask AI to refine it.

Rendered desktop stand without device reference — Example export: the stand only. Design render; not print- or fit-tested.

Tip
Reference bounds are about 61 × 96 × 8.32 mm. Complete internal geometry is not verified. Obtain real mounting, screw and clip dimensions when needed.

Copy the upload prompt and submit

Sign in to Creator center → Cases & accessories. Select Publish design → Authorize & copy prompt. Paste and send it in the same AI chat. AI will prepare the materials and upload them.

Tip
Copying alone does not submit. Wait for AI to return a model ID and pending-review status, then check the creator center. After approval, the community can preview and download it. Use Update design here for new revisions.
