Belt/Disc Sander Dust Port adapter

thingiverse

This is a dust port adapter for the Central Machinery (Harbor Freight) combination 6" disc sander and 4"x36" belt sander, model #97181 (or similar). For some reason, this sander doesn't come with an easy way to get the dust out. It has two dust ports: * Disc: 19mm (3/4") OD * Belt: 40mm OD This adapter connects to a 308mm long piece of 3/4" ID flexible tubing that goes to the disc dust port, and to a 2 1/4" shop vacuum hose. All three pieces can be printed at once on my 230mm x 155mm Flashforge Creator Pro bed. I printed them in ABS, The bottom piece has a couple of very small holes where some STL fixup happened; I just put some hot-melt glue over these so they wouldn't make noise. The 3mm holes around the perimeter of the adapter printed a bit too small for me to use 3mm hardware, but I drilled them out using a 3mm bit and used some 3mm x 11mm pins that I had to help align the parts while I glued them together. You could also probably use screws (3mm or #4) in these holes.
