This is meant to be a platform adapter for you to bolt on an extra pair of cleats. The flat size of this print is for the cleats, and the knurled side is for foot contact. You should be able to twist the cleats in an off with your foot or hand. Instructions I haven't printed this yet but since it will be weight bearing it should be high infill.
