How we built a machine to open bags all day

This turned out to be an interesting build with challenging design constraints and a really satisfying outcome. This is custom, purpose-built design for a specialized operation, but it could be easily modified for a variety of applications.

This had a little bit of everything - helical rack and pinion gears, stepper motors, vacuum suction cups, linear guide rods and bearings, perfectly placed snap rings, press fits, insert nuts, and tons of 3D printing.
