LESHP/SINIS Z1 3D Printer Radial Fan Duct & Bracket

Having abandoned my attempts to produce an acceptable fan duct design for the stock fan on the Z1 3d printer, (as sold under the brands "EZT", "SINIS" & "LESHP"), i've moved on to a larger radial fan - similar to that on other printers - a "DF5015SM".

Fan Duct:
Version 1: Single exit air duct
Version 2: Three-way exit air duct

Also included is a bracket that will allow you to mount the fan to the Z1, using the two unused threaded M3 screw holes in the top of the Z carriage.
