Author's Note: this post has taken a long time to get written - so long, that I already have my 2018 Hactoberfest t-shirt and stickers! It's content spans mid-October through December. I've done my best to make it a cohesive whole.

This project was built for Classroom Technologies & Events at the University of Washington.

We have a hammer drill that has a vacuum collector attachment, and we wanted a collector that could use different kinds of filters. I took the existing dust collector and designed an exact replacement that would take any kind of 3M respirator filter as the filter element. This allows using different kinds of filters and for the filters to be replaced. The parts involved were manually reverse-engineered on paper with the device and a set of good digital calipers. The replacement parts were designed in Autodesk Fusion360 and 3D printed on a Prusa i3 MK2.
