Philips Hue smart button mount

The Philips Hue smart button comes with a single mount, though we needed an additional one so that my kid can have it close to her in her mezzanine bed during the night.It's design for SMÅSTAD bed, which has 18mm side panel, but if needed I can create a custom profile for other width. It also has a 9.5mm diameter and 6mm deep hole behind, to fit some magnets in there.This is my first model and profile, so I'm sure it can be improved, please share your improvements.
