Playing with this model should help make Ackermann steering geometry more intuitive, and get you to think about practical considerations like packaging and max steering lock.

Different arms will create positive, zero or negative (anti) Ackermann, but which is which? It may not be as obvious as it seems!

What are the mid-arms for?

This model is dual-colour, but requires only 2 switches so no need for a multi-colour printer. Works best with layer height of about 0.2mm or less.

CAD model included. Go wild.
