NOTE: THIS WILL NOT ADD DUST COLLECTION TO A SAW THAT WAS NOT DESIGNED FOR THE ORIGINAL PART. THIS FITS A SPECIFIC VERSION OF THE DE708.
My father-in-law is a very talented artist and maker, building elaborate stage sets for his local community and school theaters, among other projects. He has a lovely, enviable workspace a few steps outside his door, stocked with a full wood shop.
He recently contacted me and asked if I could reproduce the Dust Extractor nozzle for his beloved DeWalt DW708. The part is somewhat fragile, and having been knocked a few times, repaired a few times, he discovered, to his irritation, that DeWalt had discontinued the part, classifying it as "obsolete". There is no replacement option.
Long story short: I designed a replacement part in Tinkercad and it works quite well. I've printed a few for interested people, but I am making this available through Shapeways to provide a better, stronger part, without relying on me, the weakest link, to get the job done. I entered this design in a Hackaday.io contest for "Repairs You Can Print" contest. I won an honorable mention! You can read more HERE:
