As other have suggested a sticker is cool if you are in the game but keep in mind you will definitely have to change it in a couple of months also writing with a marker(paint) on it graffiti style won’t survive the everyday abuse … If you want a clean look I would try to cover the white words with a sharpie ( ink ) might last longer still not a permanent solution… But keeps the clean esthetics …
Hate to tell you but 3d printing Is not the right manufacturing process for the job … You may have It work out but thers no reason to melt pellet plastic into a somehow precise 1.7 mm diameter wire spool so that you can make a noozle go round for hours… Just buy a pipe … No matter what it will be cheaper more precise and sturdier …
