Ninja did everything to dissuade me from fixing the broken button on my coffeemaker, but where there's determination, there may be results! This STL should work as a replacement for the power button on the Ninja coffeemaker found at Amazon here https://www.amazon.com/Auto-iQ-Frother-Baskets-Thermal-CP307/dp/B07FX73Y7H/ref=sr_1_11

I've included a picture of the broken button. Basically it connects to the casing in the front cover of the circuit board via a flimsy 1mm x 4mm strip of plastic that will break after repeated use or if you push it too hard. Ninja's clear button is offset because it has an LED on the board which shines through where you push the button to make it illuminated, while an offset rectangle presses the tactile button. This STL fits nicely where the previous button was with a little play so that it doesn't get stuck. The fact that it's not connected to the body is not a big deal because the plastic touchpad in the front keeps it in place.

When taking the unit apart, don't worry about the bottom. I did and Ninja threw all sorts of tricks with the screws and their locations to stop users from opening the bottom. You just have to take the two covered screws behind the water container off with a long phillips and use a credit card to pry the two pieces off each other. You also will not have to take all the connectors on the mainboard off, but undo a single covered screw near where the pot goes and just pry the tabs that hold the mainboard clipped to the case.

The button will likely work as replacement for the other 5 on the board, but I didn't have a broken one. I did consider breaking them off and replacing them preemptively because I didn't want to take the damn thing apart again, but decided against it.

Cheers!
