A clip to hold bags secure to those collapsing frame garbage bag holders. I lost the original ones and I couldn't find replacements. Made a quick little model and printed 4, been using them all summer while camping with no issues.
If they break or fail from the sun eventually its not a great loss and I'm happy with how they have been working.
For best results print 4 with one of the flat faces on the build plate.
The author marked this model as their own original creation.
