Frequently asked questions
If your answer is not here, read the step-by-step guide.
How it works guideDo I need an account to use DrawSTL?
No. Open the editor and start drawing right away. No account, email or installation is required.
Is DrawSTL paid?
No, it is free. Adding shapes, templates, share links and STL downloads are open to everyone.
What file format do I get?
Models download as binary STL in millimetres. Slicers such as Cura, PrusaSlicer, Bambu Studio and OrcaSlicer open the file directly.
Where are my projects stored?
Projects are saved automatically in your browser storage (IndexedDB) and are never uploaded. To move one to another device, use a share link or a .drawstl file.
Does it work on phones and tablets?
Yes. Phones get a simplified touch editor: add shapes, templates, move, holes and STL download. Detailed work such as sketch to extrude is easier on a tablet or computer.
Will my model be printable?
Union and hole operations produce a watertight (manifold) solid, so the slicer reports no open surfaces. The editor places the model on the bed and warns when it exceeds the printer volume.
