Parallel Movement Steering Demonstrator Fidget

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. The linkage connection pins should be oriented as shown for lengthwise strength and will require supports. If they are rotated upright, they lose significant strength.

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