Here are a couple of pics of the one I broke. The tang on the wire end broke off when the bike tipped over, so I superglued it back on (you can see that repair in pic 2). But the vibration and rough roads finished it off; it was dangling from the wires halfway to Seca. The nut plate end broke into two pieces, which I lost, and the end of the tang broke off too. My glue joint held. And of course it still works, I just got tired of seeing the tape holding it in.
At my employer we used a number of formed ABS parts. I learned there is a big difference between virgin and regrind material. Is there a better, higher strength material available for your 3D printer? And is it possible to recycle the LED strips into a new unit? I do like how bright they are!
Do you have a link for those hand guards?
