FlashForge Creator Pro side blower fan bracket mount

This is a replica of the bracket that is part of recent editions of the FlashForge Creator Pro and similar printers with a dual MK10 nozzle carriage. It is mounted on the left side of the extruder carriage, and supports both the blower fan and the fan duct. You need this if you want to install this type of fan and duct on an older printer that doesn't have this part, for instance if you want to install my [dual duct](http://www.thingiverse.com/thing:1675208).

It comes in two versions: one with larger holes in which three 5 mm deep metal M3 threaded inserts can be installed (see photo of the original, this is the recommended method as it makes a stronger part that won't wear out by repeated disassembly); and one with smaller holes that can accept M3 bolts directly (this is good if you quickly want something that does the job). Due to the difficulty of printing small holes accurately, in either case you will probably first need to prepare the holes with a drill.
