Ultimaker 2 filament guide

--> you can find the final version here: http://www.thingiverse.com/thing:1412297

A filament guide for the UM2 to be mounted with a M3x13 screw (or a M3x16 and an washer) below the extruder.
A M5x20 Screw is required to connect the arm to the base and a 606 ball bearing keeps the wheel moving :-)
This construction is used by me to use a wall hanging spool (rotated by 90 degrees to the original mount) behind the UM2.

A FilaGuide-Basemount-V2 is added. It contains an additional guide for the filament in the base.

FilaGuide-Basemount-v3 and v3a added. In contains an additional cleaner/oiler section combined with the V2 guiding. v3a has more room for the cleaner, depending on the cleaner material used. (This version is currently under test)

V4 Base added to save material
Arm1a added to move the wheel towards the base guide
