Dust Collector adapter for a DeWalt Mitre saw

thingiverse

An adapter for a DeWalt Mitre saw's dust bag was requested by my friend. He bought a collecting bag from E-Bay, but the exhaust outlet pipe and dust bag inlet pipe were slightly different sizes (1.522" and 1.527"). I designed both connectors using TinkerCad and OpenSCAD, but found TinkerCad challenging as the internal diameter was off-center. I then used OpenSCAD to create a ridge that distinguished between the two diameters. The connector files were prepared in Makerware and printed on a Replicator 1 with default settings except for increasing the HBP temperature to 120F. Printing took approximately four hours, and there were some stray filaments during internal ridge printing, which were removed with pliers. Both connectors fit perfectly, making my friend happy and with a spare as backup.
