NEMA-17 Peristaltic Pump V2 by CopabX
by Thingiverse
Last crawled date: 3 years ago
A new and improved minimalistic peristaltic pump for a NEMA-17 stepper motor.
For motors with more power, use the U enclosure to minimize backflow.
The pump output is 1mL/9rev.
Improved: Center hub changed to spring arms to allow for printer inconsistencies and prevent binding of motor. This means smaller steppers, more bearings, or lower quality bearings can be used. Center hub also uses a nut for the set screw to prevent accidental stripping.
BOM:
Five M3x8 screws
One M3x16 screw
One M3x20 screw
One M3 nut
(Optional) Four M3 washers
Four 8mm OD, 3mm ID bearings
One NEMA-17 Stepper Motor (at least 3 kg/cm)
2mm OD, 1mm ID soft silicon tubing
To buy one check out my store on Tindie. https://www.tindie.com/products/CopabX/nema-17-peristaltic-pump-kit/
