PLA plastic, 2.1kg, 3mm, soft
2.2kg of PLA plastic with a diameter of 3mm on a spool (GW is 3kg). Specifically produced for 3D printing with the RepRap.
The material is sold on spools to reduce twisting. A decisive advantage compared to loose material is that the spools can be put in a dispenser to get them rolled off fast and easy.
This is soft PLA. A bit like rubber.
