Through MakeXYZ I found a guy locally who is has an electronics and filament supply business, Addicore. So when I needed some more filament I contacted him. It's been an up and down experience, some of his filament isn't that good, but that's not his fault. He's learning and I don't mind helping him and most of it is very good.
The problem is some of it comes on a filament spool wider than the ones I made my top-loading delivery system for. Consequently I had to modify Scottbe's filament hanger, an easy task in blender.
Clearly I also need to engineer a hanging a solution for my mini spool.
You can download my modification and Scottbe's original filament hanger on thingiverse.
