This was the first spool of filament I ordered for my 3D printer, the FlashForge Adventurer 3, it does not fit my printer, I knew this when I ordered as mine is a proprietary size and buying the right size is more money than buying a standard size and rigging up a way to feed it, which we used a box with a cut out and a pole like a PVC pipe through it. I have used 80% of this role going non-stop for the first week I had my printer with no issues. The only reason I haven't finished the role is I bought some PLA and Glow in the dark ABS to play with as well. It shipped the same time as my printer and took 5 days to get to Hawaii, during COVID-19, which so much else is taking 10-14 days to get here right now. I bought it for the price, availability and the fact it was made by the same company as my printer so I didn't think I'd have any issues with it, especially being new to printing and not knowing what I was getting into. I have no complaints what so ever, great product.
