4" Dust Collector Blast Gate

thingiverse

This is a blast gate for a 4-inch dust collector. A pinned flap must be bored out with a drill, allowing trapped dust to be cleaned out while suction from the dust collector holds it closed during use. This model is a prototype that has yet to be printed or tested. 1/14/19 Update: Initially set up in imperial units for woodworking, my Sketchup profile was modified to metric, and I re-exported the .stl files. The hole in this updated version was also expanded, as it was too tight in the original prototype. The revised files should now be easier to use.
