https://www.amazon.com/Befenybay-Filament-Universal-Adjustable-Printing/dp/B083RTMJS1?sr=8-5&th=1I'm making some that glow green now. I wanted to make purple ones. But the spool doesn't fit. I need to figure out if I can put the filament on a spool that fits.
You may need to put it a different place, but mine just sits next to the printer and feeds in. Works perfectly for 1kg spools. For smaller 500g spools I have an arm that attaches to the side rail directly above where that spool is sitting (side panel comes off easily)
