Comparison
FitPrint vs ChatGPT for 3D printable models
You can ask ChatGPT (or any chatbot) for OpenSCAD code and render it yourself. It works for simple shapes. For anything with several features, the code often renders with errors, floating pieces or holes that are too small, and you end up debugging geometry by hand. FitPrint uses a similar language model but wraps it in an engineering loop.
What FitPrint adds on top of a chatbot
| Step | Chatbot alone | FitPrint |
|---|---|---|
| Measurements | Uses whatever you typed | Asks for fit-critical dimensions, looks up product specs on the web |
| Planning | Straight to code | Engineering plan: use steps, interfaces, structure, print orientation |
| Rendering | You copy code into OpenSCAD | Automatic, in the browser |
| Checks | Your eyes | Size, fit with real objects, insertion path, floating pieces, SKÅDIS board fit |
| Fixing | You describe the error | Errors and measurements go back to the AI automatically |
| Tolerances | Generic or none | Your printer's calibrated fit gap |
| Result | Code | Verified STL + editable source with sliders |
Frequently asked questions
Is FitPrint just ChatGPT?
No. FitPrint uses a Claude model to write CAD code, but the value is the loop around it: measurement guidance, a verified CAD library, in-browser rendering, automatic checks and printer calibration.
