Robot Wall-E - totalmente impreso en 3D

Cura 4.8.
I wound up using two switches to control the tracks. No servo control for the head, although it is mounted with one. No other electrics. Has a 6v Lithium battery in the body with charger.
I used a different method for the tracks, adjusting the front gear wheel to mesh with the track better, and used the same one for the top idler; Made it all fit and it holds together. Two young boys will put it through its paces, so it had to hold up. I worked on this for most of a month plus, working out the miscellaneous fit problems, mostly with the tracks.
