DW660 Magnetic Dust Shoe for MPCNC

thingiverse

Update: 9/16/18: My install has a secured VAC hose, but others may not be as fortunate, and the VAC tower is a bit fragile. So I added a rib, thanks to Geoffrey Pitman's suggestion! A new .f3d file is attached for you to modify. Update: 2/20/18: Why not print your own brush bristles? I tried it, and it works beautifully. TPU is the best choice; PLA bristles are too stiff, even at .4mm thickness. Two STLs and the original Fusion 360 Archive are included for you to modify. This is my first attempt at a Dust Shoe for the DeWalt 660 router on the MPCNC. The main benefit is a closer suction profile to the collet, plus a replaceable brush ring connected by neodymium magnets that should press fit into the wells provided. I used 8mm diameter, 3mm thick magnets in this build. Holes are 8.05mm and 3.1mm deep. Because this holds the router base as well, print with 50% infill and three walls. The Shoe itself can be lighter if you prefer. The slot is for gluing in bristles; I made one set of short bristles for small bits and another of 1" long bristles for longer 1/4" bits. I've included my Fusion 360 file so you can make edits more easily than editing a mesh file - I'm not exactly skilled at that! By the way, this is a new bottom using the top clamp from https://www.thingiverse.com/thing:944952. I couldn't figure out how to remix the mesh from this mount, so I started over, measuring the bottom with calipers to reproduce it and make changes as needed.
