This is an oreo holder made to slide on to a mug. It was inspired by an Instructables project (https://www.instructables.com/Oreo-Holder/) but I completely redesigned it myself. The original version didn't fit standard US-sized oreos (46mm diameter) and did not fit on most mugs I had in my house. This version does :)

Print it right side up with 3-4 perimeters, low infill and supports for the the overhanging part that latches on to the mug.
