I have had a 3d printer for 2 years. started with a makerfarm i3v kit and then later custom made myself a corexy openbuilds machine.
I enjoy tinkering/building but once the printer was tweaked and done. I really have no need to use it. I have made a few little odds and ends to help fix something but it has sat idle for 4 months.

What practical home use application have you found for your 3d printer?
