Balco Printer Fan Shroud Replacement

These are replacement extruder fan shroud for the Balco 3D printer Aldi sold recently in the UK, which is itself a rebadged Wanhao i3 Plus.

The steel shroud included with the printer out of the box wasn't great: It wasn't straight & rubbed against some prints.

* BALCO_SHROUD.STL is a direct replacement for the stock item, just a little shorter.

In 2019 I've added two other versions, but these are tweaked for my own extruder and may or may not be aligned properly for you:

* AngledShroud.STL provides more clearance and a more directed airflow
* AngledShroudDual.stl - Diverts some of the airflow around to the far side of the extruder.
