Testing a caterpillar track that is printable in one piece :)

UPDATE: Here is a video! http://www.youtube.com/watch?v=nigrV9n9658

UPDATE 2: New version 1.2 of the tracks and wheels: more curve to avoid slipping

Notes:

[DONE] An idler is required to reduce lateral force in the servo axis
[DONE] The chain needs to be even more curve to prevent it from slipping out
Still need to figure out a nice chassis

In order to print the tracks, I use Cura (https://github.com/daid/Cura) and a 0.5mm nozzle.
Settings in Cura:
Bottom/Top thickness = 0mm
Wall thickness = 0.5mm
Fill density = 0%
Solid infill top = OFF
Joris the outer edge = ON

These settings will print the track as a continuous, single-walled spiral, which makes them very flexible and resistant :)
