03.) Flow Driver: BOM

This page is under construction.  Please check back soon for updates!

To simplify the process of tuning the rate of extrusion, I designed the "Flow Driver" - which is simply an arduino-based stepper motor controller.  This is not completely necessary, but makes continuous flow printing with an extruder like this one much easier.
