E3D-v5 Fan Dual Assembly for Makergear M2

thingiverse

UPDATE: I recently posted an update to this (<http://www.thingiverse.com/thing:533029>). Please check this out for the latest version, which I think performs better and lasts much longer. I've been using the new nozzle design for over 3 months without any sign of warping. So please use the new design as the old one does warp after a month or so of use. This is an E3D fan solution for the MakerGear M2 featuring built-in supports for minimal cleanup. Inspired by an Ultimaker E3D mount model, I modified a E3D v4 fan duct to keep the fan and hot end consistently oriented, added identification lettering for nozzle diameters, and included an attachment point for the larger fan duct. Encountering few issues with this design, you may need to work on getting the E3D installed on the filament guide due to its tight fit with the restrictor plate in place. Tested for about three months without any fail caused by warping, though expect some warping over time as with most cooling ducts - it should not affect performance. E3D's recent design changes to heater blocks impact positioning of the heater cartridge and nozzle; I've shared photos of differences between old and new blocks, and retooled the design to fit version 2 as well. Adjust melt temps by ~10-15°C and reduce cooling to 20% (45% max). I uploaded new duct versions with a shorter restrictor plate for easier hot end installation into the filament guide and without the restrictor plate. Assembly is straightforward, matching parts to your hot end block version. Use Noctua 40X10mm A-series fans for quiet performance. Leave comments or suggestions for improvements. Good luck making better prints!
