This works with our Basset furniture dresser. It secures the dresser drawer to the internal rail/track so the drawer doesn't just flop about when pulled open.It had gotten old and some clips broke making the drawer sort of fall out so I made this. The gallery pic is of v1 (for now - OP will deliver). v2 (stl posted here) requires less filament. It fits snugly so some sanding may be necessary. I made a v3 (stl also posted here) with larger holes since my sandpaper is packed away.
