I am creating a conveyor belt using off-shelf Adfors screen. The spool I am using is originally purposed to cover waterways of roofing from leafs, critters, small meteorites and other less-than 1 ton objects falling from the sky. As the matter of fact the material is very strong and minimal-stretch.
This is the OpenSCAD model using the same mesh for industry, creating the tractor (yellow) and the mount (gray). The mount is replaced with tooling mounts for select segments only... If you have the imaginations it rolls along and functions nicely.
The actual printed pieces are yet to be tested. I usually do this over 365 days, living near Chicago my outdoors are both cold and warm.
