Aeropress Fellow Flow Control 67mm cup adapter

This part can be ordered printed here: https://www.justway.com/project/shareproject/Aeropress_Fellow_Flow_Control_67mm_cup_adapter_1864e1a3.html

This is an extremely specific adapter to fit the Fellow flow control Aeropress filter to very specific diameter cups, where the Aeropress would otherwise not securely on top.

You can see the problem in one of the pictures, where the filter would just barely sit on the rim of cups with about 67mm diameter. This adapter helps with exactly that edge case of cup diameter.

Best printed in PETG as it will see some amount of heat. Does not come in contact with food normally but I would expect to swap this out pretty often as 3D prints are not considered food safe to begin with.
