Anet A8 X-Axis Right Tensioner 45mm

thingiverse

After witnessing [wschadow](https://www.thingiverse.com/wschadow)'s impressive [X-axis tensioner](https://www.thingiverse.com/thing:2786603) in action, I decided to create a similar design for the Anet A8 / AM8. This original creation was made from scratch, and I've included the F3D file from Fusion 360 so that you can adjust the tolerances for the bearings/z-axis nut if needed. The bearing diameter is set at 14.9mm because I found it to be slightly too loose when testing with 15.2mm. You may want to try reducing it to 15.1mm for a better fit. Similarly, the Z-Axis Nut diameter was initially set at 11.0mm but proved to be too loose as well. I adjusted it down to 10.8mm for a more secure hold. The STL files for the pulley cartridge (x-BeltTensioner) are also included in this design. To make it work, you'll need a GT2 16T pulley with a 3mm inner diameter. Please note that this design is specifically tailored to fit rods that are 45mm apart, just like the original [X-axis tensioner](https://www.thingiverse.com/thing:2786603) I was inspired by - not the Anet version from 2017 or later with 46mm between rods.
