Tough Ryobi Bump Knob

thingiverse

I began by scaling up the basic dimensions of a standard Ryobi replacement knob. Next, I incorporated a more substantial and robust top section to enhance overall durability. Utilize your original nut and top cap if you still have them on hand. After printing my first version, it served me well for an entire year without any issues. Please note that the import values are in millimeters.
