Horizontal Spool from 5.5lb Reel by Aggresive Sep 14, 2012

Description

Have just recently changed to an orca 0.43, which uses 1lb reels and a plastic guide tube. This means that the filament is easiest to feed from below the printer, as opposed to most which feed from above the printer.

This meant that the printer kept twisting the filament off of my old spool holding device.

I also had an old 5.5lb reel from reprapcentral lying about.

Inspiration struck, and I thought of this.

I'm not aware of any other spooler like this on thingiverse, as I looked before trying to re-invent. :)

This is for a 95mm wide spool, however this will only effect the guides, and could just be printed shorter.

The top piece remains mostly stationary as it guides the filament. The bottom piece rotates to unreel the filament.

UPDATE: Gap bracket.stl attaches to the top piece, and stops the filament from being able to work into the gap between the two pieces. Bolt these as close to the vertical wall of the spool holder as possible, but leave a 1-2mm gap, so that the parts can still rotate freely.

Instructions

Print:

1 x floor stand (will need support)
2 x reel idler
2-3 x spool guide
1 x spool bush (will need support)
1 x spool clamp
1 x clamp spacer
2-3 x gap brackets

-The floor stand has three holes in the side that require tapping to M8, for the 'feet'.
-The idler is one i made up when i first got my printer, and is available on thingiverse elsewhere. The centre exrusion is 52mm, this sits inside the reel. You should also be able to use any 608zz reel mounts.
-The guide is used to stop the filament unreeling.
-The spool bush could be replaced with another idler, as that is all it is essentially.
-The clamp is used to hold the top piece down, and makes disassembly easier (one nut). The spacer acts as a washer to take up the distance between the bearing and the clamp.

-Chop the old reel so that one side is just a 'plate', and tidy up with a file. This wants to be as straight as possible.

Attach the guides to the large piece of the reel, (extra holes will probably need to be drilled) (picture 7 & 8)

-Make up the floor stand with some M8 threaded rod (4x apporximately 150mm long). (Pictures 5 & 6)

Assemble the idlers and bush. Lock off one of the idlers on the stand as seen in picture 9. Place the large piece of the old reel on the idler with the bush on top (Picture 10). Put a nut on this to stop it moving about, and also to space off the top piece.

Bolt the other idler through the 'plate' into the clamp piece, and tighten up (Picture 12). This makes the top piece solid, and securable with a nut.

Place filament inside.

Drill a hole in the top piece (8mm) for the filament to be guided through. Put the filament through this hole and place the top piece onto the spool and hold down with the spacer and a nut.
