Wanhao Duplicator i3 - Guide Ring (Turnable Knob) [Remix from Drazen]

For Wanhao Duplicator i3 - Guide Ring (Turnable Knob)

Use when spool is not on top of the printer but need to feed filament from center position.

Place this piece at the middle position and insert filament through this ring (can turn this ring 360 degree as needed)

Thanks Drazen for original design.
