(revised 9/2018) Cooler for FT-5 and 713maker.com Ultralight Aero extruder mount

Human: (note! The STL for the "frame" (or cage) part has been updated to fix a reported problem with fitting at the top between the Ultralight mount's screws and the motor. With the revised "Frame.stl", no sanding should be needed now.) :)\r\n\r\n(Another note! Sept 2018: I redesigned the "Duct and fan mount for..." parts from scratch. Some people were having trouble getting their slicers to accept the old versions, and the files were pretty messy anyway. The new ones are a little easier to print and assemble, a little lighter, and no longer need the nozzle spacer.)\r\n\r\nThis set is designed to provide a cooler for use with the 713maker.com Titan Aero ULTRALIGHT Extruder mount, with either a Volcano or E3D V6 hot end, for the Folgertech FT-5 printer. It is meant to be used with a 25mm deep NEMA 17 motor (17HS10-0704S), but there's a spacer to alternately use it with a 20mm deep "pancake" motor. It provides a very rigid and lightweight cooling solution using a 50mm x 50mm x 15mm blower fan with a direct path from output to the duct outlets while pulling cool air from the side (instead of from close to the heated bed).\r\n\r\nAll parts print without supports or rafts (though a cooler or side fan would be needed to print cleanly).\r\n\r\nNote that not all 50mm blowers are created equal! I don't know of any ball-bearing types that will work with the PWM speed control provided by the MKS board of the FT-5, so unless you want to experiment, it might be best to steer clear of those. For other fans, the thing to look for is the current rating -- a 12V 0.06A rated fan will work okay, but its output is pretty wimpy. Look for a 12V 0.1A to 0.16A fan, those seem to move quite a bit more air (you may even need to turn the speed down to 50% or so in some prints, quite a lot of air gets pushed out by this cooler).\r\n\r\nNote, also shown are my "BLTouch Mount for Titan Aero" and "Titan adaptor for using 3mm ID reverse-Bowden tube"\r\n\r\nFile descriptions:\r\n\r\n Duct and fan mount for Volcano.stl: The duct and fan for use with Volcano hot end.\r\n Duct and fan mount for std V6.stl: The duct and fan for use with a standard V6 (non-Volcano) hot end.\r\n Frame.stl: A lightweight cage that goes around the motor and provides a mounting surface for the duct and fan\r\n Back plate.stl: A plate that screws onto the back of the motor and holds it in place\r\n Spacers are used to hold the back plate to the cage/frame in place\r\n\r\nFile Sources:\r\nThe Frame, Backplate, and Spacers are original designs done in Fusion360\r\nThe "Duct and fan mount" parts are redrawn in Fusion360, and are partially based on a duct design by 3D Genera: https://www.thingiverse.com/thing:2332177 and a 50mm fan mount design by Onebaldman: https://www.thingiverse.com/thing:1738499
