I have no idea what the correct term is but I think it is "spooler"
Anyway, my UP! 3d printer gets the plastic filament from a small spool, and wanting other colors (black) to play with I ordered some plastic filament from http://reprapsource.com/
So how do I get the large spool from reprap source to my small UP! spools?
What is needed to build one is:
- 6pcs of 50cm m8 rods (3x1m)
- 6pcs of 33cm m8 (2x1m)
- 4pcs Spool holder caps
- 4pcs rod holders
- 4pcs 608 bal bearings
- 4pcs Mendel footed vertexes
- 2pcs Mendel non-footed vertexes
- 4pcs M4 screws, nuts and washers.
- Some m8 nuts and washers.
Step1. Assemble 2 frames using 3x50cm m8 rods each, 2 vertexes with feet and one without for the top, like a standard mendel build. Measure all distances so they are the same, it´s not that important what distances they are at, just that they are the same so it wont be wobbly standing.
Step2. Connect the two frames with the 4x33cm m8 rods, two at the top and two in each corner at the bottom.
Tighten the nuts when it can stand without wobbling,
Now put in bearings and nuts into the rod holder. and put them where you want the spool and tighten the M4 screws. Just loosen the screw to slide it up or down to where you want it.
|It's a pretty snug fit so you might need pliers to get it in.|
I plan to make a motor for more automatic spooling but a screwdrivers works good so far, it takes me about 1-2minutes to fill up a small spool with 700g of 1.73mm filament so I will probably survive pretty long without a motor on it.

I have run it a few times and I´m under a minute now for a full spool with a steady hand ;-)
