how many meters is one spool?

Bear with me while I do some math on this one. From www.matweb.com, the average material density for PLA is 0.0473 pounds per cubic inch. So, a spool weighing 2.2 pounds should have 46.511 cubic inches in it. With a filament diameter of 1.75mm (0.06889 inches), the cross sectional area should be 0.003727 square inches. 46.511 cubic inches divided by 0.003727 square inches = 12,479.6 inches in length, or 316.9 meters. Does that seem about right?

Why did this suddendly double in price?

Supply and demand isn't BS, but it's also a bit mendacious in this context. What Amazon is really trying to get at here is what's called the "market bearing price", and it's not the same as supply and demand. To put it another way, if you think the price is too high, send the right market signals by *not buying it*. We decide the market bearing price; Amazon merely looks for it.

Can somebody weigh an empty spool for me? How many grams is the spool?

I weighed my brand new full spool after removing the clear plastic cover. 1270 g. So if there's really 1Kg of filament, the spool weighs 270 g.

What temperature should I print this color filament at?

Flashforge Creator Pro printing on glass with AquaNet hairspray I run 230°C extruder and 60°C bed temperature. When using these settings, I NEVER have a problem with prints lifting. In fact, even after cooling they don't want to release... until I put the glass in the freezer. 5 minutes later, the prints are completely free of the glass with no tugging, scraping, or damage. I love this filament. It also anneals very well.
