IKEA Voxnan shower shelf adapter

The original fixation mechanism was too big to fit behind my shower pipe, so I designed this screw-less coupling for my 25mm shower pipe

The guides that fit into the shelf itself are slightly tapered to clamp on the pipe as you push it.

I wasn't entirely sure that it would work, but it does! :)

It stays firmly fixed on the pipe, and can hold things without sliding or moving
