Ikea Grundtal Towel Rack Knob

This is a round knob addon for the Ikea Grundtal towel rack or any Grundtal stuff with similar features.

I used superglue (cyanoacrylite) to fix them to the stainless rack. Lightly filing and cleaning the surface of the rack with a metal file seemed to really help the glue adhere.

For color and smooth texture, I painted them with white 'hammered look' spray paint. Three light coats.
