This is a simple garbage bag holder that can support itself on a slightly open drawer. The intended use is to easily catch scraps in the kitchen when preparing food. It should accommodate any size plastic bag, but was designed to re-use old plastic shopping bags from the grocery store.

I printed main structure and the holder ring separately on rafts. I flipped them both 180 degrees upside down to avoid the need for supports (mostly). the little tab on the holder ring should print OK without a raft when upside down, although I did end up using a Zig Zag support in Cura to increase the quality.

I designed this in Blender 2.78b using millimeter scale.
