Here is the part that is missing from the MMU2 & MM3 kits.
The thing often referred to as "the button" in the manual.
The reset button.
No more looking for something long and small to press the button with.
Its a 4 minute print (0.21grams) and a 3 minute install worth doing.
Enjoy!
HEY PRUSA STAFF! You can add it to the official kit. I accidentally had the wrong license before.
