Desk Shelf Extension – Simple Workspace Upgrade

Looking to squeeze a bit more functionality out of your desk setup? This compact shelf extension is a quick and easy way to expand your workspace without breaking out the tools. Perfect for holding small speakers, gadgets, or even your morning coffee.

I designed this to mount directly to the edge of a desk using three 3M adhesive strips (or your preferred mounting method). It’s been holding my Klipsch speakers with no trouble at all—sturdy and reliable despite its small size.

To help test the ledge fit, I included a small 5mm-high piece. This prints in just 6 minutes with no machine calibration. It’s a great little project if you’re looking for a fast, practical print that makes a noticeable difference in your setup.

Feel free to remix, resize, or add your own flair. Whether you're organizing your gear or just making your space feel a little more dialed in, this shelf extension is a fun and functional upgrade.
