3018 CNC Dust collector

I've created this simple dust collector for my 3018 CNC, for when I cut carbon fibre. It's working better than expected, all the carbon dust is eliminated.

The bottom can be easily detached for tool change, and cleaning, it's attached with 6 + 6 magnets (with 5mm diameter, and 2-2.5mm thickness) 

It doesn't need any modification of the standard spindle holder, it clamps on it with 2 M3 screws.
