4" Dust Collector Blast Gate

thingiverse

This is a blast gate for a 4" dust collector. There is a pinned flap that you will need to bore out with a drill. This will allow trapped dust to be cleaned out but the suction from the dust collector should hold it closed when in use. This is a prototype that hasn't been printed or tested yet. 1/14/19 Update: Being a woodworker first, my Sketchup profile is set up in imperial units which means that the .stl files were freakish so I changed my Sketchup to metric and re-exported the .stl files. I also expanded the hole in this update, it was too tight in the original prototype. The files should be easier to use now.
