Centering and Driving Flat Belts

Would it be possible for someone to posts a few pictures to show how it attaches with the rollers. My team has wanted to try this before, and this would be a nice help.

You can see there really isn't much to it. Wrap the tape while spinning the roller, and wrap more densely in the middle. It doesn't take much to keep the belt centered.

In the various incarnations of our arms and handlers we drove the flat belts in a couple different ways.
1) using rollers made from 1" OD aluminum tube. Where the belts were located, we wrapped the rollers with 1/4" wide strips of 1/16" thick bump-on adhesive backed urethane from McMaster.
2) using 1" wide crowned rollers that were 3D printed. STEP files for these parts can be found on the CAD models found in this thread. We made rollers for both 1/2" hex shaft and 3/8" round keyed shaft.
