The planned obsolescence part of the Krups GVX2 coffee grinder - the power button that breaks per design.Print the button at 0.1 solid. To take the coffee grinder apart: Take both dials off (use a flat screw driver and nudge the out), then on the bottom, there are 4 tabs on the inside. Separate the halves and you will see them. Towards the front and halfway back. Pry the halves apart enough to push the top towards the bottom and it slides apart pretty easy. The cover slides up and over the top of the grinder. The front panel then slides up and away. Take the broken button and salvage the blue acrylic insert, and the clear acrylic part. Glue these to the new button and screw it in place. Reassemble.
