Just make one with an apple. You just core it and carve out a bowl and there ya go. Dont core it too much just however big you want it.

If you meant that you were making a long-term pipe, you could use a dresser knob and carve out the flat side and make a hole for the stem, or get a socket and use that. Apples are fun, sometimes you don't even need to carve out the bowl if there is a big indent around the stem
