Kobo clara HD button

Kobo Clara's button seems to get destroyed pretty easily. So here is a replacement button that worked for me. You would have to open up the back cover and unscrew the screen from the front cover, so you can put the button in its place. Screw it back and close the cover. Make sure to have the hole on the side where the little light is. 

(I printed mine on the A1 mini with default settings and “0.08mm High Quality”)
