My 3D Printed Peristaltic Pump

Hi Onshape and fellow users.

I designed a peristaltic pump using Onshape. I 3D printed it using a Ultimaker2 printer, and other parts include some ball bearings, flexible tubing, a DC motor gearbox, and some circuitry. It's purpose is to pump blended food into a person's feeding tube when they cannot physically eat, it was built for my grandfather while he was treating esophagus cancer.

Check it out here: 

It is entered into the Boca Bearings Innovation Contest. If you like it, please give me a vote. Thanks.

The project is CAD'ed on Onshape, while I was in China, using the 4G network and I also had to hop through a VPN service (I think AWS was blocked), on a Microsoft Surface tablet. I think it's a pretty good testament to the usefulness of cloud CAD. The public Onshape workspace is linked here.

    That is fantastic.  Really awesome to see a direct implementation of OnShape like this.  I had to play around with peristaltic pumps at my previous job at a medical assay manufacturer, they're neat contraptions.  Great work on the model and functional real world application too.

    fantastic, this may be the first time that I actually see somebody make something truely useful with these newfangled 3D printers at home

    Thanks everybody

    It's really not hard to find useful things that can be 3D printed. You just need the right opportunities. The bracket on the back of my car that holds my rear view camera is 3D printed. The thing that holds my phone and Qi charger together is 3D printed. My keyboard is tilted forward with a stand that's 3D printed. My PS4 is modded with a 3D printed dock for hard drives, and the hard drives have 3D printed cases that look like NES cartridges.

    I hope I'm inspiring people.
