Universal 40mm Radial Fan Conversion Kit

Converts a 40mm fan (with roughly 23-25mm center hub) into a radial fan weighing 22 grams. Everything can be printed without support, just rotate them because my STL files are always sideways. I suck at making parts that fit together (and many printers do too) so this is all glue together, except for the fan itself. The blades are springy to accommodate multiple hub sizes, and the included adapter ring can be used on smaller hubs. I have also included my cooling shroud for attaching to the end of the fan to cool both the print and the cold end of the extruder. Mine moves much more air than the fan it came from, and makes less noise. See instructions for details.
