One of the real beautiful things about 3D printing is being able to save something from the garbage heap; in 30 minutes of CAD, 45 minutes of printing, and one trip to my parent’s cabin.

This giant inflatable wasn’t able to maintain a seal after the o-ring cracked. My brother (a proper mechanical engineer) sent me (a hobbyist CAD modeler) the drawing and I got him the part in time for his yearly lake party.
