I never think about what will happen in future, tomorrow I might as well fall under the bus and die. Planning way ahead doesn't help me, I just jump into whatever I find interesting then ride the tide till it's no more.

You can also check on YouTube there is a Canadian I think? Company called ProtoPasta which also makes filament in small shop.

Filament market I think, isn't big enough for the large companies to dominate.

And other thing is logistics, I make locally I can offer cheaper rates to local buyers shipping locally.
