I own a Neff induction stove. I lost the original magnetic FireTwist button, so I 3d-printed a replace.

You need a strong magnet 6mm diameter and 3mm thickness. If you glue this magnet to the part on the first buildplate, this is allready working button. But for easy usage you should glue this to a 50mm acrylic disk and also glue the outer ring. The little bit smaler ring is a jigg to be able to glue the black-white part exactly in the center of the acrylic disk.

For the final version I used an AMS, but I also builded prototypes where I glued the back parts onto the white part. Please leave a comment if you want also a version that can be printed without AMS.

I chosed the suface pattern and the infill pattern intentionally to optimize the optic properties.

I tested it with two different neff induction stoves. But I'm still not sure if it works also for other products from Neff or Bosch.

I also created personalized versions, feel free to add logos to the white surface.

Be carefull with superglue, the fumes build a foggy layer on acrylic glass.
