A while back, we began having our 3D Universe materials produced in 750g spools in addition to 1kg spools. This was done primarily for our Ultimaker customers since the 750g spools fit more easily on the dual-spool holders on the Ultimaker 3 and Ultimaker S5. It turns out, most people using 3D printers designed for 1.75mm filament prefer the 1kg spools. So we're going to be dropping our 3D Universe PLA and ABS 1.75mm materials in the 750g weight. As a result, you get to take advantage of some significant savings!
