Скачать или смотреть 3d printed mini syringe pump with parts from optical drive

My another project with optical drive parts... I was asked if these stepper motors would have enough force to move a syringe so I decided to test it.And as you can see, they can and do it well.This frame is designed for 5ml syringe, with stepper motor there is possible great resolution to achieve.Only 3 parts to print.

This can be used for liquid measurments/precision feeding, its not medical or cyber junkie equipment

Parts needed from optical drive:
stepper motor
linear shaft

Other parts:
syringe - im using "diconex 5ml 3 part syringe", I don't know if they are available in other countries, if not there is model which should have same size: https://s.click.aliexpress.com/e/_AmWxks
mouse limit switches - im using these, model D2F-L3.They are optional and required only if you would need to have some feedback from device https://s.click.aliexpress.com/e/_DDg...
