anet a8 x belt holder tensioner

thingiverse

This is a combination of two upgrades I'm particularly fond of, allowing them to collaborate seamlessly. To assemble this setup, you'll need an M3 nut - if you've been building an A8 like I did, that's the correct size; otherwise, you may want to seek out one. Additionally, an M3 screw of suitable length will be required for your belt and tension requirements. If I were to revisit this project in the future, I'd allocate a bit more space for the third screw on the bottom tension side. You might consider going back to grab the original Grabber file; I had to significantly loosen it to accommodate a belt, and even then, it was a tight fit.
