This holds apple earbuds that have volume control. I used some hot glue and some failed prints to keep it in. I used an extra v-slot screw to attach it to the printer. I had to make it come over after every print and click the volume down button on the earbuds. I cut out a little piece of cork and glued it to the the hot end cover to press the earbud button. I just messed with the g-code a little. This is mine but you will have to edit it a little bit to fit your printer:
G91
G1 E-6.5 F3000
G90
G0 X180 Y215 F9000
G1 X201.7 F9000
G4 P10
G1 X201.7 F9000
G4 P800
The 201.7 is where it clicked the button for me but it will be different for you. So when you change it make sure to change it everywhere in the code.
