About this 3D model

I designed this device for my new CNC-Mill. only plug in a vaccuum cleaner and all span and dust will be succed up - and it cooles the milling spindle at he same time. Works pretty well :) why selling expensive aluminium parts when you own a 3D Printer ? - no Support Material is needed for pinting added a newer Version - is a bit smaller - may help to avoid collisions in some cases have fun
