Anet A8, X-belt tensioner

thingiverse

Here's a simple belt tensioner designed specifically for the X-belt - no need to use a longer belt by adding this component. The following parts are required: 1 M4 nut, 1 M4 screw measuring 40 mm in length, and an optional washer and spring. Since my Anet A8 came equipped with extra springs, including one identical type for the heated bed, I opted to utilize one of them. A slightly stiffer spring would offer even better performance.
