Just an idea...

Hey, have you ever been frustrated with trying to attach something to a round extender like the polycarbonate, aluminum, titanium, or steel extenders? Well, i was just thinking that if it was possible, to alter them so you could see the connection points, so you could put thuings on them more precisely and with less trial and error tests. Just an idea... :?

Actually making the connection points visible on the bot wouldn't be possible.  I could reskin the extenders so there would be spots where the connection points are, but that would be a lot of work and it would look kinda weird, especially on the polycarbonate extenders.

But it's actually not that hard to rotate extenders precisely once you figure it out.  They rotate in discrete increments of 10 degrees.  So, just count the number of times it "clicks" while you're rotating it.  To rotate it 90 degrees, just rotate it 9 clicks, for example.
