Supports are required but set the angle to 80. It holds all the tools that come with an Ender 3 V2 and a few extras too. All tools are held away from the gantry so they don't interfere with the machine at all. It is designed to be a tight fit to the extrusion so it stays put once fitted.
Remixed from https://www.thingiverse.com/thing:3877505 to fit the official dual-Z upgrade from Creality and widened the smaller wrench hole to fix the wrench that came with my printer. Original text removed from body of model.
