Anet A8 - X Axis Belt Tensioner Idler

thingiverse

My take on an X Axis Belt Tensioner for the Anet A8. 2 versions available: 8.75mm Inner Gap and 10.00mm Inner Gap. ### Update includes correct placement of the nut. I apologize for this mistake. If you printed the old design, secure the nuts in place with glue. The new design also benefits from gluing the nuts for better performance. Note that the design is not symmetrical; the side with the nut should face towards the back of your printer. Important: To install this version, you will need extra belt length. If you cut the belt just enough when building your A8, this version won't work for you. Instead, consider using [this alternative](https://www.thingiverse.com/thing:2415085). To assemble this tensioner, you'll require some extra M3 bolts and nuts along with a pair of washers (optional). Although they can be tricky to install, having them between the bearing and the sides of the idler is beneficial. PS: This design should work seamlessly with [this modification](https://www.thingiverse.com/thing:2471354). I hope you like this creation!
