4" Cable Driven Blast Gate

This is a cable driven blast gate for 4" Sewer pipe (also know as DWV pipe). Only the flanges, cable guides, and label are 3D printed and the rest of the components are made from 1/2" plywood, although it would be possible to print those as well. Step files included so you can reference the plywood parts.

The system uses go-kart throttle cable (or bike brake cable) to actuate the gate.

Hardware used is 5MM bolts and nuts.
