Ender 3 Z-axis Support and Filament Roller Combo! No support material or disassembly required! This part was designed to fit perfectly into the top cross member of your Ender 3 or CR10 printer, supporting the Z-axis screw and providing a smooth rolling action for filament feeding without kinks or harsh angles. Two 608 bearings (8mm x 22mm x 7mm bearings) are recommended for completion. One bearing presses into the roller and one in the z-axis support after sliding onto the frame.

The roller guide pin features a twist-lock design, easy to install and explained clearly in this text. Simply line it up with the mating slot in the guide and rotate 90 degrees clockwise to lock (or 90 degrees counterclockwise to unlock). In the unlocked position, use a miniature flat head screwdriver to pry out the guide pin if needed. It is suggested to loosen and re-adjust your z-axis motor mount to ensure everything lines up properly with the new support. Re-tighten afterwards. You may also need to adjust the z-axis screw by loosening the motor coupler screws and pulling the screw up in a twisting motion to make it sit higher in the support bearing. Re-tighten afterwards.
