Whittle is free, open-source parametric 3D CAD for everyone: first-timers, makers, designers and engineers. Sketch a shape, pull it into 3D, round the edges, and export it for 3D printing, laser cutting, CNC or other CAD software.

It uses a real CAD kernel (OpenCascade), so you get exact solids, true fillets and STEP export, not just meshes.
