Ender 3-series nozzle size indicator dial

thingiverse

I change nozzle sizes a lot and I liked Ken448's idea of a nozzle size indicator and dial that sticks onto the end of the Y axis, so I made a remix of it that let me play with recessed numbers as part of the project. It prints WAY more cleanly in standard PLA than in more complicated PLAs like blue silk, and you want a 0.2mm nozzle to make the numbers work - but as the white model shows, they very much do work. Fill them in with whatever infill you like, I use nail polish but whatever works for you.
