very simple drawer-latch

thingiverse

I created a temporary solution when I needed it, as my desk has a sunken carpet on one end preventing access to adjustable feet. Drawers would roll open due to vibrations from my desktop bot. Instead of fixing the issue, I used these clips that attach to drawer edges, holding them shut until needed. To open, simply flex away the tab and pull. Closing is normal, with the drawer slipping past the tab to lock in place. Attach with foam mounting tape for easy use.
