In the past, I have found 3D printer parts with a bolt to be great for tensioning.

Thanks!

Since the bumpers have to be 2 inches off the ground according to 2014 bumper rules, the bottom half of the boxtubing wouldn't actually contact the bumper. so we turned it sideways to get some more contact area. But the bumper system is still a work in progress, so we may change it again if we think of something nicer.

and actually the design can be used with versablocks if we need to (the drop center is the same). we are just hoping to avoid spending money (and robot weight) on them.
