Anycubic Mega I3 Y-Axis Belt Tensioner Inspired by https://www.thingiverse.com/thing:3098565 but greatly simplified and designed to work seamlessly with a standard GT2x6 pulley. It's likely to fit other printers as well. To ensure a perfect fit, replace the two screws with slightly longer ones right away. The tensioner adds 1mm plus any additional washer you decide to use.
