Magnetic Dust Collection Chute

thingiverse

This is a dust chute with a 2.5" port for connecting to a shop vac. It's held to any metal work surface (e.g. a router table or a drill press) with a row of four 3/4" diameter by 1/8" thick rare earth magnets. The Fusion 360 file is included if you want to use different size magnets - just change the appropriate parameters. I printed this originally with a 0.75" + 0.1mm clearance diameter circle for each magnet, but I had to do a little sanding and pushing to get my magnets in, so the version here uses 0.25mm clearance instead. You can use a dab of glue or pool epoxy on top of the magnets to hold them in place. Print with 5 walls in your slicer - this will actually print faster than the default two or three walls, because there's practthe print head will make nice smooth circles instead of having to change direction all the time for the zig-zag of the infill.
