I created a "trash can" that uses the plastic bags you get with your groceries. Simply put the bag between the brackets and hook the bag's handles to the bottom of the print. The prints attaches to the wall using one 3M Command Strip for each bracket.
The print in the photo was printed at 25% infill, with a raft, and tree supports in Cura. The brackets were oriented so that the bag handle hooks faced up.
The author marked this model as their own original creation.
