Is MakerNest CAD Studio really free?

Yes. Every feature, including STL export, is free forever. There is no watermark, polygon limit or paywall. The marketplace only takes a cut if you choose to sell a model.

Do I need to install anything to use the CAD tool?

No. The whole app runs in your browser using WebGL. It works on Windows, macOS, Linux, ChromeOS and iPadOS — no signup required.

Can I import existing STL or OBJ files?

Yes. You can import STL, OBJ and GLB meshes, then sculpt, boolean-cut or remix them and re-export.

Which 3D printers does the build-volume previewer support?

Bambu A1 mini, A1, P1S and X1 Carbon; Prusa MK4; Creality Ender 3; Voron 2.4 350; Elegoo Mars 5, Mars 5 Ultra, Saturn 4, Saturn 4 Ultra and Jupiter; Anycubic Photon M5. The exported STL works with any slicer (Bambu Studio, OrcaSlicer, PrusaSlicer, Cura, Lychee, Chitubox).
