Funnel

It seems like my funnels always disappear, they always get left out, fall in the dirt, or get broken. You don't save much by printing them when you can buy a pack of them pretty cheap. But this is a good way to make sure you always have one on hand, and save a trip to the hardware store.  You can buy them for about a dollar a piece. I like to have 3 or 4 on hand of different sizes. Having the ability to custom build the exact size is extremely useful too. I think that makes it worth  $0.50 a piece. The ones I made were small. They will work good for things like oil in a lamp or similar needs.
