Paper Bag Rim

This remix was inspired by Occasionally_Inspired's paper bag rim which helps keep open a paper bag so you can use it for whatever you like. I like using this for recycling, dry compostable items, and collecting shredded paper since my recycler only collects this if it's contained in a labeled paper bag.

v2 Notes: I realized there was an error in the model which left open faces to be poorly interpreted by the MakerBot slicing engine which wasn't apparent in Cura. I've updated the model accordingly and the problem should be resolved.
