I needed a push button to replace my old one badly printed with ABS on the extruder of my Anet A8.
So i designed and printed my own under 20 minutes :D

This teeny tiny thing is a QOL improvement of the A8, try to push on the bare screw on the extruder for a minute or so, i dare you :P
its very easy to print and install.

the base of the button is rather large, it should be okay for most Bowden mounted extruder. Haven't tested on a direct drive, too lazy to replace my bowden extruder with the direct drive one for a button lol.

If your printer is well calibrated enough, it should be a push fit, not too tight, not too loose.
I'm including the Solidworks file to tinker the model to your own fitting, if you plan to do a remix of it, please put me as the original creator of it, even if its just a button.
