MPCNC Spindle Sawdust Shroud

I created this to stop the fan on top of the MPCNC 52mm Chinese Spindle blowing sawdust everywhere.
It bolts onto the top of the spindle with a couple of M4 bolts.
The idea is that you cut off the top of a soft drink bottle, cut a series of very thin slits into it and screw it into the shroud.
It seems to work very well on my setup, and the sawdust is not flying around the room any more.
