I’ve received a few tips on this, and somehow it keeps slipping by. The fab@home project immediately reminds me of reprap. This is a completely open source hardware project for rapid prototyping/3d modeling. In the past, manufacturing something like a turkey baster bulb required injection molding. The project wiki has full details on building your own, including manufacturing houses to get all the acrylic laser cut. It looks like you could get your hands on one of these pretty easily if you don’t mind making a dent in your wallet. Thanks to [nickjohnson] and [peter B]. [peter B] also noted that the cornell boys have an even nicer one that they use to make zinc-air batteries and artificial muscles.
