I came across this on facebook. So far only a placeholder web page, but I’ve emailed them. They claim if you have 10 or more empty spools they will pay for shipping.

So that we all don’t have to email them, I’ve already done it and will post the reply.
Filamentfactory.ca was asking for them. I also just realised this morning that my email to them asking for more info has been stuck in my outbox for days now, which would explain why I haven’t heard back yet.
