improved rotor for NEMA17 peristaltic pump
thingiverse
improved rotor parts for NEMA17-improved peristaltic pump. My stepper motor has a shorter axis as the proposed one and thus used to break the provided rotor plates. This design has a wider guide for the axis to prevent slipping. No additional parts are required. I printed it in PETG but also ABS and PLA can be used (not tested). Made using Autodesk Inventor 2021.
