Ender 3 (pro) filament guide wheel

thingiverse

I designed my first project around a bearing from my workshop, which had a diameter of 26mm and a bore size of 10mm. To assemble it, you'll need an M5 x 20 screw and nut. Installation was straightforward using the existing screws on the lead screw nut. The guide wheel consists of two identical halves, eliminating the need for supports. By gluing these halves together, the bearing's interference fit keeps them securely in place without additional adhesives.
