I have printed several items for around the house but more along the lines of 'it broke and is no longer available/too expensive to replace'. Items include: brackets for my wife's full length mirror, hinges for the toilet seat/lid, mounting bracket for the aerial, stuff like that. My mancave gets a few items too; cell phone stand, desk organizer, business card holder, and so on. Toys for my son too...

But that's only when its not running for work. I do a ton of prototyping for work.
