Monoprice Maker Select Plus Rear mounted fan duct

This will probably work with either the cocoon create or the wanhao I3Plus. This will give you a complete, unhindered view of the nozzle as it is printing from the front of your printer. To install this, you will need to relocate the PCB. Here is a link to how I relocated it... https://www.thingiverse.com/thing:2973514 This fan duct can be adjusted (up or down) depending on the allowance of the nozzle to the heater block. This is why the screw holes of the fan are elongated (instead of just plain holes). This is also a 2-part print. The fan duct is the major item, but it also needs to be connected to a spacer that is positioned between the fan duct and the bearing block. Because of this, you will need to use 2 pieces of M5 screws (preferably 20 mm in length). The spacer is slanted a few degrees because the fan has to be slanted when mounted --- because the nozzle is not centered and is actually on the left side of the bearing block. The fan for this duct will still be the normal stock fan that should have come with your printer.
