Yet another peristaltic dosing pump
thingiverse
This is another variation of peristaltic pump. I utilized an HS-755MG servo whose electronic components were compromised and connected the power supply (5V) directly to the motor. Next, I added "vitamins" consisting of 6pcs of 625 ball bearings, several M5 screws and nuts, an M3 threaded rod, and a spring as evident in the images provided. As tubing was used standard silicone aquarium hose with diameters measuring 4/6 mm (internal/external), the servo possessed sufficient torque to handle it efficiently. The pump is showcased in action at https://www.youtube.com/watch?v=piET5409c1g.
