Replacement step stool rubber foot

This is a replacement foot for a generic step stool with 5/8" OD steel tube legs. Helps keep the legs from marring wood floors. The bottom of the foot is domed just like the original.
Why throw out the step stool just because it lost its feet? Or why bother going to the hardware store looking for replacements only to find they're sold out (as happened to me). This part is easy to print and needs no support.
Openscad source is included for your modding pleasure. Just change the variable "OD" for different size tubing.
