This is actually a pretty good application for home 3d printing.<p>I&#x27;d say that you&#x27;d be looking at 8-10 hours per print with a consumer FDM (extruded plastic) printer on the default settings.<p>If the printer is correctly configured it will probably be more durable than you&#x27;re implying, and even if it only lasts a year you could always cheaply print more.
