Cleaner Motors, Cleaner Workshop! I recently got tired of all the dust buildup on my CNC’s stepper motors and cables, not to mention the mess it created visually. So, I designed this neat and simple motor cover specifically for my NEMA 23 motors. It cleans up the look, routes the cables neatly, and most importantly, helps protect the motor connections from dust and debris. Easy to print and install, this little cover really upgraded the overall feel of my workspace.
