Trash Can Espresso Knocker

thingiverse

Knocker that mounts to a standard under cabinet pullout trashcan in the US that use 13 gallon tall kitchen bags. The trashcan top is approx 14.25 X 10.50 inches Knocker pops on and off easily when you need to change the trash bag. I wanted to smooth the top of mine, so the cracked paint you see in the picture is my poor attempt to do so with filler primer and paint. :-) Had an idea to take a 1-2 mm silicon sheet, cut and mount it across the round part to soften the knocker but haven't done so yet...
