It's specifically designed to mount on the newly redesigned effector platform and the included
30mm squirrel cage fan.
Download, extract and load the layer fan model into MatterControl, just as you did for the
PEEK fan. The printing parameters are the same. Make sure you've got the same slicing configuration
you used as last time and hit the Start button!
Fig. 21-1: Looking good!
When you're able to remove the part from
the print bed, insert the tiny squirrel cage fan into the shroud as shown below.
