Bar Clamp - Twist-On

One of my Prusa Mendle Y-Axis [Smooth] Bar Clamps cracked as a result of it being slightly over-tightened while building my printer. The printer's been performing just fine, but I recently I wanted to upgrade the Y-axis PLA bushings to LM8UUs and,
a) didn't want to risk the cracked bar clamp failing completely during upgrade, and
b) didn't want to start tearing the whole printer apart for the sake of ONE bar clamp.

So here's a bar clamp that:
* is easy to retro-fit without disassembling your Y-axis,
* has a 'developed' surface, (vs a simple hole) to clamp around the smooth rod, which together with the clamp arms being wider at their base, makes this clamp almost incapable of being overtightened,
* has an 'anti-twist' tooth and socket feature which positively locks together the clamping 'arms' during installation. This effectively prevents the outward displacement of the clamping arms that otherwise occurs when tightening an 'asymmetric style clamp' such as this.
