This is a simple model that allows you to clean the female taper on a CAT 40 milling machine to prevent chips from getting lodged between the mating faces. Requires 6x thick felt strips glued into the slots on the taper. if you cannot get thick felt you can fold it over on itself.

If there is interest I can also create models for other spindle sizes. Let me know. I will not be able to verify fitment however.
