Spooler kit;

Can spool anything that can be fitted onto the axis in betwen the centering cones, Filament, Wire, String, as long as is not hoist cables or other tough to spool things.

If you want to spool pretty fast you will need a level winder.

Here is how it works without a level winder,  you can produce 1 Kg in maybe 5 but mostly 7 hours.  With a level winder you can extrude up to 10 -15 kg per hour.  With this version maybe 5 Kg per hour.

Can be used manually with a spool clamp, or with an electric motor.

One stand for roller axis
one breadboard base

various pulleys

one centring cone without pulley
one centring cone with 20mm short pulley

one centring cone with 50mm long pulley
Various motor supports (Nema 17, Nema 23 and a couple of others)

You need to buy elsewhere M6 studs long 300mm or more, M16 nuts (be generous, you will use them a lot) M16 nylock nuts (minimum 4) M16 wide washers (at least 8) interior diameter 16mm or 18mm “O” Rings (plumbing stuff) you will ned minimum 4 of them, M4 nuts and bolts, M5 nuts and bolts.

2Bearings Outer Diameter 35mm, inner diameter 16mm, 11mm thickness (or near by)
each axis takes two bearings they should be snug fit, zero play but not forced in position, if you need to force them, better stop, take them out and sandpaper work the hole around gently, and try again., once they are in than take the 300mm threaded stud (may be even slightly longer, but not shorter) and at one end fit a nylock nut until you see a thread of the stud going out of the nylon lock, than tuck in a washer, than one “O” Ring, than the pulley of your choice, than another “O”Ring, than another washer than put the stud in from the non flat side all way through to touch the bearing, at the other end put in another washer, than a nylock nut, and while holding the stud with a clamp somewhere thread that nut into the system until the washer grips onto the bearings a bit, just enough to have zero play without stopping the bearings from twisting, and test if the pulley has a nice grip solid with the axis, if not, close a bit more the nuts, like a quarter of a turn. Now is ready to fit cones and align with other elements like the motor pulley, the level winder pulley and the level winder filament path (trial and error till it works)

As transmission belts I am using some Kitchen elastics, wide 10 mm or more, thick at least 2 mm and at least 100 mm long when measured flat (technically they are 200 mm around the circumference) but have at hand also shorter and longer versions. They are cheap, easy to replace and have a good grip.

You need Structural Silicone (also known as sealant glue) to spread onto the cones surface and their grip channel on the back, and let it dry a few days before using it, that is to give a grip to the cones on the spools.
Some pulleys you will note have some outer obstacles around, you can use them as they are or cover the pulley with structural silicone until the outer obstacles are covered by a mm or two making your pulley a rubberised one, let it cure a few days before using it.
