Harbor Freight Rotary tool mini vacuum

thingiverse

In this project, a $10 Harbor Freight rotary tool (part numbers 69451, 68986 or 97626 are interchangeable) was transformed into a mini hobby vacuum cleaner. For the filter material, a Bounce Fabric Softener sheet used in the dryer was utilized, but other options like screen door screen material or PC fan filters can be employed. To print the parts, settings of 10% infill, two walls, and a .30 layer height were used; rafts and supports were generally necessary, except for the handle which printed support-free. Your mileage may vary. A video demonstration is available at http://www.youtube.com/watch?v=adz_8Ef0znY.
