Another 3-zip-tie tensioner

Secure your belts by using zip ties; this was discovered while trying Nophead's 1/2 twist technique. This method ensures the flat side is over the non-toothed pulley. However, as of 2018, I no longer use the 1/2 twist method since purchasing the correct idler pulley is now just as affordable. Regardless, I still employ the two-zip tie method which is adjustable, cost-effective, and lasts for years.
