MCP
Use it from your own AI.
Claude, ChatGPT, Cursor or any app that speaks MCP can build in your open Extrudle tab. You watch every step, and it all stays editable.
- Open Extrudle and press Connect AI. It copies your own link.
- Add the link to your AI app.
Included in the Maker plan. Or skip the setup: Build with AI is built in.

Questions
Good to know.
Which plan should I get?
Free if you want a full design tool for personal and hobby use, and to learn to design things yourself. It's free forever.
Maker if you want your designs kept private, to sell what you make, or to design with your own AI (Claude, ChatGPT and others) as much as you like. It also has £2 of AI built in each month. Pay monthly, or pay once for life: Lifetime is for the first 500 only.
Pro if you'd rather design mostly with the AI built in: £12 of it each month, and Ultrafast.
How quickly is the AI used, and can I buy more?
It depends on the design. What the AI built in charged to make these:
A shelf bracketabout £0.10
A remote caddyabout £0.10
A flexible T. rexabout £0.20
A flexible geckoabout £0.25
So Maker's monthly AI makes about 20 designs like the bracket or 8 like the gecko, and Pro's about 100 or 50. Changes you ask for afterwards, higher reasoning and Ultrafast use more. Each reply shows what it cost.
The month's AI starts again each month. When you need more, top up £5 at a time on Maker or Pro; top-ups are kept until spent.
What does "use your own AI" mean?
On Maker, you can connect Claude, ChatGPT, Claude Code or Cursor to your open Extrudle tab (Connect your AI… in the project menu). It builds in the app with the same tools as the AI built in, as much as you like, and your own AI's plan pays for its thinking.
ChatGPT needs Plus or above; Claude's free plan allows one connector, but its limits run out quickly. A plan of about $20 or £18 a month, such as Claude Pro or ChatGPT Plus, is plenty to start.
Which AI model and reasoning should I use with my own AI?
Right now Claude Opus 5.5 and GPT-6.1 Sol work about equally well, so use whichever you have. Medium reasoning suits most designs; choose higher for big designs with many parts. Models change quickly, and we'll keep this up to date.
Do I need an account?
No. Design, check and export without signing up. A free account keeps 10 projects online, on any device; Maker and Pro keep as many as you like.
Are my designs private?
On Maker and Pro, yes. On a free account we may feature designs you save. Designs saved while on Maker stay private even if you stop.
Can I sell what I make?
On Maker and Pro, yes: prints, the files, or products made with them. A free account is for personal use.
Which printers and files does it work with?
Any. Export 3MF, STL or STEP for your slicer (Bambu Studio, PrusaSlicer, Cura and the rest). Import STL, 3MF and STEP models, and SVG or DXF drawings.
What does Lifetime include?
Everything in Maker, for good, including its AI each month, for one payment. It's for the first 500 only.
What happens if I cancel?
Your plan runs to the end of what you've paid for, then you're on a free account. Your projects stay, and top-ups can still be spent for 30 days.
