This Free AI Skill Lets You 3D Print Anything
You will install the free CAD Skills collection in your AI agent, ask it to design a custom part (I build a Stream Deck Plus desk clamp), and end with a 3D model split into printable parts that you can inspect and revise.
Was Sie brauchen
An AI agent: Claude Code, Claude Cowork, ChatGPT Work or Codex
The CAD Skills repository (free and open source)
A 3D printer, or a friend with one
An idea for a part, plus its official dimensions or a product page
Schritt für Schritt
Copy the CAD Skills repository link
Open the CAD Skills repository and copy its link. It works with Claude Code, Claude Cowork, ChatGPT Work or Codex, so pick the agent you already use. I use Codex in the video.

Ask your agent to install the skills
Paste the repository link into your agent's chat and ask it to install the skills. It reads the repo and handles the installation, including the skills, the viewer, the Python it needs and the plugins. Expect about two to three minutes (mine took 3 minutes 33 seconds).
Install promptHey Codex, I want you to install this set of skills. Can you please do it for me?
Start using the skills in the same session
Your agent may say you need to restart the session. You don't: once the skills are installed, you can use them right away. Tell it you want to use them and describe what you want to build.
Describe the part you want
Explain what the part is for and the size you need, and ask the agent to check the official specifications before building. I ask for a desk attachment that holds my Stream Deck Plus about five centimeters from the desk so I can use it while standing and filming.
My build promptHey Codex, I recently purchased a Stream Deck Plus and I want to build an attachment for my desk that is going to help me put it like five centimeters away from my desk so I can actually use it when I'm standing and filming videos. Can you please check all of the specifications that you need from the official site from Elgato and then build this clamp for me? Remember to also include the screws. I'm going to be 3D printing this.
Say that you will 3D print it
Tell the agent up front that the model is for 3D printing. It will then split the design into the separate pieces you assemble afterwards, instead of one model that only looks right on screen. Ask for screws if your part needs them.
Add to your promptI'm going to be 3D printing this.
Let it find the official dimensions
The agent breaks the job into steps and fetches the official product data online. You can also give it your own measurements instead. Modeling takes longer than installing: plan on 10 to 15 minutes or more (my first run took 26 minutes).
Inspect the finished model
Open the model in the 3D viewer, or in your browser, and check how it is built. Look at the 3D-printable copy too. My clamp also had an opening in the back for routing the USB cable.
Revise, then print
If something needs changing, tell Claude, Codex or whichever agent you use what to modify. When you are happy with it, drag the files into your 3D printer software and print.
Worauf Sie achten sollten
Your agent may tell you to restart the session after installing. It is not necessary: the skills work in the same session.
If you don't say you will 3D print the part, you may get a single display model instead of separate printable pieces.
The first model takes a while (mine took 26 minutes). That is normal on your first run with the skill.
Ask the agent to check the official product specifications, or give it your own dimensions, so the part actually fits.
