Coffee Cone Adapter

I have a favourite mug that is too big for a #2 coffee cone. This adapter lets me make coffee without having to worry about the cone slipping off the mug. It will work with mugs up to about 109mm diameter at the brim but might slip off one of less than 106mm. I have included the SketchUp file so you can modify it to suit your needs.

A note of caution; This one was printed in PLA. The reason the adapter elevates the cone is to keep the PLA away from the hot water, otherwise it will deform due to the heat. The added ventilation does prevent this but be wary.
