Grohe dual flush button

I designed this part when my dual flush button broke (model Grohe Skate Air 38505000).

Two lower snap locking fasteners, which hold yellow part of the button, broke (see images), replacement button would cost more than 30 EUR.

I used hairdryer to warm up the 3D printed part to make it fit on the oval surface where the fasteners should be positioned.

I brushed both surfaces with sand paper and used super glue, resting overnight.
Make sure to position the part so that the bottom part fits into the small channel on the base of the button (chrome part).

With simple modifications, I believe it can be modified to suit other models.
I'm uploading the CAD model as well for easier editing.
