a perastaltic pump of my own design

grabcad

I needed a cost effective peristaltic pump and couldnt find one, no one was lesser that INR 3,500, almost 60 US dollars. There was no simple design over internet and even grabcad which i can trust would surely work upto the mark. So i decided to make my own design and printable also. I thought why can we pinch the tube on the diameter, why cant we pinch from the 90 degree of it? this way just by tightening the bolt I can get required amount of pressure on the tube and it depends how much i tighten the screw or the bolt. I confess, I did a lot of wrongs, but finally came up with this design and its really working very well. I dont know whether somebody prior to me have done this or not, but then it does'nt matter, Its open to you all guys, If you have any questions, ask me, I will try my best to upload the videos or pics whatever is with me to make you understand right now i am in the process to develop it more, so far it worked well. But i have faith you will understand just by looking at the model of it. Note: The photos here are not the renderings but camera clicks, sorry for black and white, i dont have a very good camera, these are real clippings of the pump with motor but the previous design and it is fully working and giving almost 1/2 ml water per revolution.
