Printrbot E3D Dual Cooling Fan

thingiverse

UPDATE: I've designed a new rear fan shroud that will keep temperatures stable at temperatures over 250C with kapton tape as an insulator; otherwise, it can hold about 205-210C without tape. If you're only printing PLA then you don't need to insulate your heater block. However, if you plan on printing PETG, ABS, or any other material that prints over 200C, you'll have to wrap your heater block in kapton tape. Upload for this updated file will be later tonight. Keep an eye out for the Rear_Fan_shroud_R2 in the thing files. This adapter is designed to attach two blower style fans to a Printrbot Simple Metal outfitted with an E3D hotend; because of the shorter and fatter nature of the hotend, I've been having troubles with the supplied fan shrouds with blower and conventional style fans. So I decided to design my own. Firstly, this is very much a work in progress. This is the first completed iteration (April 5-2016). Secondly, everything should be easy to print. Some supports may be needed depending on how adventurous you are. The 'Rear Fan Shroud' assembly is split into two parts for easy printing, either super glue or acetone weld these parts together as seen in the assembly screen shot provided. This will interfere with cable chains. That's a fact. You'll also need to re-route some wires to make room for the Rear Fan Shroud. This is something I'm working on but I want to get the design out there and get people testing the cooling ability of this assembly first; tackling compatibility is next.
