Summary

The school's caretaker requested some drinking fountain knobs because most of the drinking fountain around the school are either missing it or its broken in some way.

Printed with 90% in fill on PLA
Printed with support
Requires some cleaning before use
Requires drill and tap for set screw to mount it properly

Not sure the brand of the drinking fountain. I printed them a bit smaller at 98.5% of original size. So far they seem to be holding up to the daily abuse.
