About this 3D model

This is my design of a peristaltic pump or hose pump if you translate it directly from german.I built this pump for reseach to gather basic hands-on knowledge of the inner workings.If you have a MakerBot/3D Printer you can start right away. I built it in a few hours with common parts i had at hand.Unfortunately you definitly NEED a very flexible silicone tubing, to get it really working. I did my first try with a short piece of tube i cut from our fish tank - this was definitely to hard for the ABS. unfortunately i was to eager to pump some water, so i did, but the contraption got too hot and broke.The Pictures are from the rebuilt, but this time i'm waiting to get the silicone tube. Currently there are no mounting holes for a motor. i used my electric screwdriver for testing. Gearmotor is planned, but i had to determine the required torque with this build.
