Wanhao i3 Duplicator Extruder Fan Grill v2

You know those two little bits of tubing that keep falling and roll under the printer every time you unscrew the extruder open?

Gone.

To help with the holes on the fan grill, there is a small plastic stop in each hole that helps with bridging. Once printed, pop them out with a 3mm screw, pushing from the inside.
