For the longest time, I have had some small guitar equipment lying around on my desk. Eventually, I decided that it was time to find a proper place for them so I created this 'floating' shelf to attach directly to the notestand.
This particular notestand is around 25mm in diameter and the semi-circles on the shelf and clamp have a diameter of 28mm to fit a piece of 2mm neoprene to provide enough clamping force and to prevent paint-scratches on the notestand.
The holes in the shelf are currently sized to accommodate M3 plastic inserts.
If you have some different dimensions you would prefer add a comment and I will try to upload a new version to adjust them accordingly.
I would recommend extra bed adhesion support in each corner of the shelf, as it is otherwise very prone to warping.
