New: automatic fillament reel

Here is the new automatic fillament reel.
good for 3 and 1.7mm fillament.

No motors required

 In stead of winding it on an outside reel, this one
 winds inside of the reel.
This way you will never get spaghetti.
No matter how big the original diameter of the packed fillament was,
it will always fit inside of the reel, because it wants to go wider.

the fillament goes through a 4mm tube towards the extruder.
Perfect for Cartesio and most other 3D printers
