I can’t take full credit for this, I found the spindle mount on thingiverse, but added the vac attachment to it. I then made a vacuum nozzle and a PVC to vac hose adapter. It’s working pretty good as can be seen in the video. The project had other issues (as discussed in the video), but the shop vac part worked quite well. My garage didn’t have a layer of dust all over it when the cut was finished.
I will need to remember to empty the shop vac after every use. There was about a half inch layer of dust caked on the paper filter.
