A nice little (tiny) shelf for an Ikea Fjällbo open shelving unit.

A round channel is provided to route a cable tie; loop this through the shelf and around a support to secure this to your Fjållbo. Sized specifically for a Nest Speaker, but could hold other things. This model is for the right/rear post, just mirror it to orient on the other side.

Print without supports. Use a cable tie to secure it.
