Received, and thank you very much.

Two 'discoveries' to pass on:

- Once the first spools are half used the nylon spins in the shell freely, which means that I can hang the shell stationary (on the corner that sticks out) and the filament comes out of the one section that's open (to the left of the corner).
- The new spool's "lips" are a bit looser than the first shell. I guess it's random manufacturing variation, but the filament feeds out of the new spool more easily than the first one.
- Both spools rotate better horizontally than vertically. I put them on a broom handle, next to the printer and sticking vertically, rotating on a round plastic washer.

I've been printing Nylon for days, so plenty of motivation to test new spools. Thanks!

Thank you, Sir! As you might imagine, it's extremely busy here as any help you can provide to us all is greatly appreciated. If you don't mind, I'm going to send three spools so you can experiment to the fullest. Therefore, please don't hesitate to try as many solutions as you have time for. Again, thank you for your time and help.

Print 2 each with general settings.
Slot plastic shell for center rod and wire tie to hold the two sections.

With the pliability of Nylon we are designing a newer spool and a couple new packaging forms for reduced overseas shipping costs.

So how does this function as a 'hub'? The coil of filament comes in a plastic shell that doesn't have a hole in the middle, so it can't function as a "spool" that I can see. This shape looks like it might fit onto the two plastic bumps in the shell, but the bumps are conical, so this wouldn't snap onto them, and there's no hole in the middle, so I don't see how this would work as a 'hub'. What am I missing?

After some testing, the answer to "how does this function as a hub" is "extremely badly". The problem isn't really this "hub" - the real problem is that the filament isn't tightly would onto a spool, it's loosely looped into the plastic shell. This means that when the printer pulls the filament out, the spool doesn't rotate. Instead the filament pulls from one spot (stuck in one spot by the "lips" on the shell) with the filament inside the shell pulling tighter until it can't be pulled any more.

While the plastic shell that it ships in looks clever, it's not functional as a hub. Perhaps it's more boring, but perhaps Taulman should buy some standard spools and ship the filament on them. Or at least tell people to carefully wind the filament onto a spool before using it.

Don't take this as a negative of the filament - it's great stuff.

Cool. Godspeed in your future endeavors!

I added your page to: http://reprap.org/wiki/Printin...

It will be a very interesting development to see this  and other kinds of filament being pushed to the addicts. Especially as its real easy to hold a specific temperature these days.

 Thank you, for adding our Nylon Materials to the wiki!
With the elimination of delamination, pliability in smaller parts and strength in the larger parts, we're anxious to see what new ideas/designs will become part of Thingiverse and beyond.
