This is a low-friction adjustable spool roller designed specifically for the Ender 3. It's mounted securely on top of the frame, working best with a direct drive mount. To get started, you'll need some essential parts like four M3 bolts and four hex nuts, along with four 608ZZ bearings. Next, print two copies of the SpoolRoller model and four BearingSim models. Please note that assembling this roller requires a basic understanding of how to put the pieces together.
