We were tired of the Costco trash bags being left in the box and on the ground. So I made this to make my pantry a little more organized. I hope it helps you in the same way. Attached to the wall with two screws of your choosing.
Printing Instructions:
3 walls / perimeters
.3mm layer height worked well.
I used PETG, but feel free to use PLA, ABS, etc.
