Printable caterpillar track

thingiverse

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 Instructions Scad code is messy, but i wanted to publish the promising results ASAP :) 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 :)
