I finally have a visual answer to your question! Just hashed out CAD for the lane blocker this evening. It is a .25 in thick piece of ABS driven by a rack on the blocker and a pinion mounted to the aforementioned servos. Each will ride on two .25x.25 in shoulder screws with 10-24 threads (McMaster 91259A533).

The process has been detailed in our most recent blog post, which includes a download link to the calculator we used to design the rack teeth.
