Hi

Now the printer is up and running I have a roll of glow in the dark filament but it still has a problem spooling out so I after looking around the office to see what I had this is what I came up with.

You will need :-

CBT training kit box
Year planner tube or similar which is tight fit in reel.
Filament reel
Self explanatory really. The friction between the box and the tube is an effective way of stopping the reel over feeding.

The reel and the mandrel fit inside the box once disassembled.
