This is a remix of the excellent design of Ralf’s Perstaltic pump. I printed his pump and built it to his specs, but I found that the small stepper motors would not really run the pump consistently or with enough power.
I decided to modify the pump to accept a Nema 17 stepper. This gives the pump PLENTY of power to push whatever liquid that you’re trying to push. I had to beef up the bearing holders a bit. I also added some mounts. There’s a single pump mount and a 4 pump mount. (I’m using to add fertilizers to my aquarium, so I use the 4 pump version).

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
