Printrbot Plus- Polakium type Direct Drive Extruder Platform and Fan Shroud.

These files will create an extruder mounting platform and cooling fan shroud to be fitted to the Polakium Engineering or my own X axis carriage for the Printrbot Plus Ver 1. The extruder is of the 1.75mm fliament variety fitted with 0.4mm nozzle.

The extruder I used for this design was created from parts available from RobotDigg.com. Here is a list of the components. Obviously they are generic for the most part and can be acquired anywhere.
