Melitta single cup pour through adapter

thingiverse

I've got a Melitta single-cup pour-through that uses a Melitta #2 cone filter, and I also have a Contigo cup. However, the locating ring on the filter holder isn't quite compatible with the rim of my Contigo cup, so it doesn't sit very stably. To fix this issue, I designed an adapter that fits around both sizes and provides a solid base for the filter holder. If anyone needs to modify the design to fit their specific size requirements, I've included the Fusion 360 file for easy adjustments.
