Guitar Style GT2 Belt Tensioner

thingiverse

I required a way to fine-tune the belt tension until it was perfectly calibrated. To accomplish this, I utilized a 20-tooth openBuilds GT2 Pulley. However, I needed to drill out the bore by 1mm to accommodate the guitar tuning mechanism. The result is a setup that works flawlessly, but does come with a bulky design. To share my design, I created a Fusion 360 part which can be found here: http://a360.co/2d5zsfn
