Husband and wife duo. The 3D printer started as the husband's toy, but the wife eventually discovered the 3D printer is super fun and staged a 3D printer takeover. The wife loves printing tiny animals for her students and designing fun or useful things. The husband lovingly tolerates the almost complete takeover of his 3D printer by the wife and wisely does not question how much she has spent on filament. Now, when the husband gets to use "his" 3D printer, he likes to print Nintendo items, things for their kids, and things to display his Taekwondo accomplishments.
