Tevo Tornado/Creality CR10 Single Motor Dual Z w/ Tensioner

thingiverse

This upgrade is a must-have to eliminate slop in your Z axis movement on the Tevo Tornado and Creality CR10 printers. It's incredibly easy to print, clean, adjust, and takes less than 5 minutes to install using only the tools that come with your printer and a small wrench, socket wrench, or pliers. For this mod, you will need an M3 and M5 tap for the pulleys and top bracket. Use the original lead screw on the new belt-driven side, and the 525mm lead screw on the motor-driven side.
