mpcnc dust shoe remixed

thingiverse

I created a modified version of brandroid64's dust shoe for mpcnc. I used harbor freight neodynium magnets to connect the base to top, securing them in place with superglue. The number of magnets was likely excessive. I installed threaded rod 5/16 and tee nuts, drilling several holes around the periphery of each tee nut and securing them with 3mm screws and nuts on the top piece of dust shoe. A piece of 2mm thick hobby foam from hobby lobby cost just a dollar and served as the basis for the skirt, which I held in place using 3mm screws 8mm long with lock washers from Lowes. The tube was firmly attached to the groove in the top piece using superglue. The parts were printed with 3 walls and 100% infill, while the support was printed with 15% infill. To assemble the dust shoe, rotate the top piece 90 degrees so that the magnet holes face upwards and the circle for the shop vac hose faces downwards. I printed the top piece with support, which easily detached from the shop vac hose depression. Next, rotate the bottom piece 90 degrees so that the magnet holes face downwards and the perimeter around the edge faces upwards. Printing the bottom piece with support was also easy to do, as the support removed cleanly from the bottom magnet holes. The tube did not require any support during printing.
