Raise3D N2 heat shield and fan mount

thingiverse

This is a combination heat shield and fan mount specifically designed for the Raise3D N2/N2 Plus. This version only works with the V2 head, making it a valuable addition to any 3D printer setup. I created this remix of the excellent front fan mount by Sylus: http://www.thingiverse.com/thing:2102446. I was tired of having to remove my insulation wrappers around the hotends every time I wanted to change nozzles, so I designed this heat shield. It effectively blocks the hotend heat from affecting your prints while also providing a fan that helps improve print quality and speed. To change nozzles without any disassembly, just use my modified hotend tool: http://www.thingiverse.com/thing:2183719. Heat your hotends to 140 degrees Celsius, insert the tool from behind the hotends, and unscrew the nozzle. No more disassembly needed! Just remember to unload your old filament completely before removing the old nozzle. You want to ensure the isolation tube is completely clean before changing nozzles. To print this model, use polycarbonate or other high-temperature filament with a layer height of 0.25 mm. I used 25% infill to reduce weight and improve print strength. I positioned the model with the back of the shield touching the base, which prevented the slicer from putting support material inside the fan air channel. After printing, use 1 inch kapton tape and cover both sides of the shield with 3-4 layers, then cut out the nozzle holes and air vent. The kapton is really only needed on the inside, but having it on both sides helps prevent filament from sticking to the hotends. The fan I used is the same as the one Sylus used in his original design: http://www.thingiverse.com/thing:2102446.
