Please see more information in the video.

You need to print 3 left and 3 right parts to make the full circle. The outer part is 56cm in diameter when printed.

Two versions are available when it comes to thickness which controls distance from the wall: original (26mm) as used in the video which gives nice floating effect and a slimmer one (15mm) which I haven't tested or used but might be useful for some scenarios. Step file can be used for further modifications if needed.

Print hot with 10+ walls to avoid any potential issues.

Use superglue to glue parts together and I used “mounting” silicone (there are many types that are designed for mounting heavy things) to glue whole mount to the back of the mirror. Make sure to glue and mount this well to avoid any breakage which is not my responsbility.
