32mm Vacuum Hose Filter

I was vacuuming my work table after trimming some 3d prints and I accidentally sucked up a wire... doh. This filter allows small 3d printing shavings and other small items to be sucked up, but catches larger items (the filter holes have 2mm radii/radiuses).

Created by slicing the bottom half of the source object off in Netfabb Basic and then adding the top filter section in 123D.

Update: I just discovered this thing. https://www.thingiverse.com/thing:2590150
