Cut Lab · Find your crowd

Different work. Different starting points.

Every generator shows the finished contour as you work and creates a portable DXF—not a locked project file.

The lab

“The engineering is the main character.”

Skepbuilt follows projects worth doing anyway—from fabrication and machines to instrumentation and energy experiments.

Plans, data, drawings, and parts are shared when they are genuinely useful and ready.
