I needed a simple desk organizer. I looked around here, but I didn't find any that looked like it would match the decor of my living room where our family computer desk is. So, I made my own. It's basically just a cup, with a wider tray base for stability and to provide a place for those odd things you need to keep handy at your desk.
The outer edges of the tray have a smooth filet so that removing items––especially coins and other flat things––are a cinch to just slide up and out.
If you need to keep paperclips or other metal things handy, I have one version where one of the larger compartments in the tray is magnetized and has a slight depression to keep a pile of them. I've included a photo of the magnets I used if you can find the same ones, great. Otherwise, I've also included the Fusion 360 archive and the STEP file of the same in case you have a different size magnet. (Mine was 5.1mm x 5.6mm x 6.2mm, IIRC).
I printed it in Prusement Galaxy Black and it looks pretty elegant on my desk. No need for supports anywhere. The one pictured was printed a 0.2mm layer height and looks pretty great, but if you want the filets and the recessed paperclip area to be extra smooth, I'd recommend a 0.1mm layer height or thinner.
