Peristaltic Pump Controller Mount

thingiverse

This is a simple holder for a 5x7cm prototyping PCB with holes for a potentiometer and an LED. For the pump, I used the design of silisand (https://www.thingiverse.com/thing:1134817). The schematics of my circuit can be found in the images above. I have also included the software (.ino) for the Arduino MCU and the f3d file so that everyone can customize the design to their needs. # Parts - Nema 17 Stepper - https://bit.ly/2UZBT9T - Arduino Nano - https://bit.ly/2UZC4C5 - DRV8825 - https://bit.ly/2PzryeR - Buck Converter LM2596 - https://bit.ly/2vq9pqU - Buzzer - https://bit.ly/2J4UWc1 - Capacitor 100uF - https://bit.ly/2GMEpaW - Touch Sensor - https://bit.ly/2UIhl0P - Potentiometer 10k - https://bit.ly/2UL9xLC - Green LED - https://bit.ly/2Vvo7eP - PCB Terminal - https://bit.ly/2Px02P9 - Prototype PCB 5x7cm - https://bit.ly/2Vvol5F # Cost - Nema 17 - $8.99 - Arduino Nano - $1.99 - DRV8825 - $0.95 - Buck Converter - $0.38 - Buzzer - $0.19 - Capacitor - $0.08 - TTP223 - $0.09 - Potentiometer - $0.40 - Green LED - $0.01 - PCB Terminals - $0.12 - Prototype PCB - $0.14 - Diverse Screws and PCB Headers - approx. $0.50 - 3D Printed Parts - approx. $2.50 - Total - $16.00
