When I first got my 3D printer it came with a small bundle of filament. Unwinding this as my prints were created was fine initially, but after sitting and watching builds for hours on end it eventually gets a little less interesting.
Whilst sitting watching builds I was able to ensure that the filament was feeding correctly, but obviously if I was to leave it creating things on its own I would need something better to feed filament.
About the same time I also pretty much used up all the filament I had so I ordered a 1Kg spool from eBay.
Now, when this arrived I realized that I needed something to hold the spool whilst the printer is printing, so I did what pretty much everyone with a 3D printer does... I built something.
What we have here is a triangular stand which holds a 1Kg spool of fillament and allows it to feed fairly freely to my Mendel printer. I did think about using bearings, but it does not really seem to need them.
Of course... the irony of my first useful print being a spool holder is not lost on me !!!

Print 2 sets of this file and then tap the pieces together, leaving the top cross brace loose until you drop in your filament spool, then you can tap it in to place.
The cross bars should be pretty tight and not require glue or anything.
