Text to STL — describe it, print it
“A clip that holds a 6 mm LED strip on the underside of a shelf.” Type a sentence like this into FitPrint and you get an STL file that is ready for your slicer. Unlike text-to-3D tools that guess a shape, FitPrint asks for missing measurements, uses your printer's tolerances and verifies the rendered model before you download it.
- Input
- A sentence, optional photo, optional measurements
- Output
- Binary STL (+ .scad source)
- Typical time
- 20–90 seconds per design step
- Slicers
- Any: Bambu Studio, PrusaSlicer, OrcaSlicer, Cura
What makes a good text-to-STL prompt
- Say what the part does and what it attaches to: “holds a 26 mm broom handle on the wall”.
- Give the fit-critical numbers if you have them (diameters, thickness, hole spacing). If not, FitPrint asks.
- Name standards when they apply: M3 screw, 608 bearing, IKEA SKADIS, Gridfinity, GoPro mount.
- Mention constraints: max size, no supports, must be printable in PETG, must survive heat.
From text to STL in four steps
- 01Write the description.
- 02Answer up to four measurement questions (or let FitPrint assume reasonable values).
- 03Check the rendered part — the real objects are shown as translucent ghosts so you see how it is used.
- 04Adjust sliders, then download the STL.

Frequently asked questions
Is there a free text to STL generator?
FitPrint's first part is free (two messages, automatic checks and fixes included). After that, Premium is 7.99 € per month.
Do I need CAD skills?
No. You describe the part in words. If you know CAD, you also get the OpenSCAD source to keep editing.
Can I upload a photo of the broken part?
Yes. Photos help the AI understand the shape; fit-critical dimensions should still be measured with calipers.
