Customize + collect

Make it fit. Mix different parts and quantities in one job—here, six designs become eleven pieces.

Example Cut Lab job: one 106B address sign, two straight timber connectors, two L plates, two gussets, two eye tabs, and two tube saddles. — Actual job tray · example parts · click to enlarge

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.
