We got a request last week from a customer for the inside diameter of the Bean Vault tube so he could 3D print a funnel to aid in filling.
Felt that it would be nice to whip one up in CAD for him and then thought it might be a good idea to share the file with everyone else out there.
Here’s a link to the file. To note, if you do 3D print this funnel, be sure to use a food safe filament.
