E3Dv6 Shroud and 40 mm Duct w/ Magnetic Coupler for 6x3mm Magnets

thingiverse

I've modded the original with right-hand filament cooler so that the magnets I have lying around from my R/C hobby will fit perfectly. The magnets are six-millimeter round shims and two point nine millimeters thick. Here's a link to the magnets I used, which fit really well: http://www.banggood.com/100pcs-N50-Super-Strong-Disc-Magnets-6mm-x-3mm-Rare-Earth-Neodymium-Magnets-p-997163.html. However, I didn't reduce the diameter of the original magnet mounting holes, so one-quarter-inch magnets will also fit well. By request, I've added a version with a seven-millimeter lowered mount called "30mm_wnn_exotic.stl" and another with an eight-millimeter lowered mount that should work with an E3Dv6 with VOLCANO heater. I have a VOLCANO lying around but haven't installed it, so let me know if it works well for you. I've also added a part called "for clearance adjustment," which allows you to adjust the clearance of the joint by ungrouping the parts, stretching the insert to the desired size, slipping it into place, and cutting it out with your choice of STL editor. The most convenient way to do this is with the free 3D Builder from Microsoft, which comes with Windows 10. Printer Settings: Printer: Anet A8 B with E3D v6 bowden and RAMPS 1.4 Rafts: No Resolution: 0.1mm with 0.4mm nozzle Infill: 25 Notes: I've printed the combo with white ABS using Brim, and it came out very well, lying on the fan side, where the forty-millimeter doesn't need any support, and the thirty-millimeter only needs support under the magnet mount. The thirty-millimeter fits really well and tight on the E3D v6 and causes the magnet mount to require only one pair of magnets in the lower position. The weight of my ABS combo is fifteen grams without magnets and fans, and the complete thing with magnets, both fans, and a small three-LED bracket weighs forty-four grams.
