A dust collector has a vacuum coupling for connection to a vacuum source such as a portable vacuum cleaner or other suitable source. A vacuum reservoir is formed from a chamber between nested interlocking receptacles. A variable density pattern of inlet holes through one interlocking container into the vacuum reservoir provides better flow and capture of debris, while multiple inlets within the vacuum reservoir provide even and consistent suction. A variety of inlet geometries are presented that are suitable to a variety of purposes.
