Similar story for my ironing board: A nylon runner wheel cracked in half, breaking the folding mechanism. Modeling a replacement in CAD (I used fusion 360), 3D printed it, little drilling to get the axle to fit, and the ironing board was back working same day. It felt great to fix a problem like that - there’s something very techno-utopian about it, like you’re living the dream of a Wired article from 1997 predicting a future where we will all effect household repairs by replicating spare parts.

But that’s happened once in the three years I’ve owned a 3D printer. Simple mechanical part failures just don’t seem to happen that often.
