This is a simple Parallel movement demonstrator. This is one of several solutions to the problem of steering and parallel control.

It will need (3) M3x.5 @ 8mm screws, for which I highly recommend pre-tapping the holes in the base. They're modelled threaded, but threads that fine often need a little help.

This model is roughly the same style and size as the collection of simple mechanism models by Adam. I highly recommend a look!
