Prusa i3 belt tensioner (and other printers should work)

Note - all these types of clip-on belt tensioning systems are temporary fixes that will cause vibrations in the belt, which in turn feed back into the print. A proper stationary tensioning system is needed for quality prints. • Version 2 uploaded today, July 13, 2016, featuring a lighter and slightly shorter design. Noted at high speed with small printer movements, the belt vibrated and the tensioner knocked against the carriage belt holder, creating unnecessary noise. I took inspiration from this version but felt it added too much tension to the belt, so I created a lower-tension alternative. You can find the original design here: http://www.thingiverse.com/thing:81991 This clip-on belt tensioning system has slightly less tension than most designs, aiming for a balance between tight and loose. During installation, it's easy to get the belt too tight or too loose; this version provides a gentle, more forgiving approach. (PS, don't forget to vacuum around your printer!)
