    Greg´s Extruder 9:47 3D Print Model

    Summary
    Well this is a remix of https://www.thingiverse.com/thing:961630 extruder, with very little changes to satisfy my needs. One of that is 9:47 gears ratio that in my case give me a 24mm3/s filament flow with 1.75mm filament. This design use:
    3 – 608 bearing
    1 – M8 50mm Hobbed Bolt with hob centered at 23.5mm (this can be changed with washers to your needs).
    1 – M8 Self Locking Nut
    1 – Nema 17 Motor
    2 – M4 Allen Bolt 54mm long
    2 – M4 Hex Bolt
    2 – M4 Washer (to hold pressure springs)
    2 – Extruder Pressure Springs
    1 – M3 shaft to hold idler. A m3 bolt with nut can be used.
