Cooling Fan Duct for CTC Printer (MK8 Extruder)

After changing a few things on my printer I found that the cooling duct I was using to cool the print was not ideal so I designed my own together with a bracket to hold it onto the MK8 extruder. This bracket also replaces the two nylon spacers that sit between the fan and heat sink.

Two different fan ducts are included, one is 10mm longer than the other. The one fitted on my printer in the photo is the long version

The printer that this is designed for is the CTC i3 Pro B but it may fit others.

Although this is not a remix, some inspiration was taken from the previous fan duct and bracket that I used.

Supports are not needed for either part, but you may wish to use them on the bracket if you have trouble with overhangs.

Update I have added two new versions which have a smaller nozzle opening which should give a more concentrated air flow.
