These stair clamps are for CNC routers with wasteboards that have m5 inserts. These clamps differ from other models because the stairs feature large steps (1/8" tall) that are angled in such a way to trap the opposite steps of the teeth - less slippage.

In addition to the clamp, a large m5 bolt is needed.

3D Printing: 30% Infill It is recommended to print the stairs and clamps on their sides to increase the resolution of the steps.
