OBK001 (ULTIMAKER)

The Olsson block-kit is a third party upgrade for the Ultimaker 2 family which allows you to quickly and easily change nozzles. This allows you to change nozzle sizes to suit your project. A larger nozzle for faster printing, or a smaller nozzle for more details. It's also useful when printing abrasive materials as it's cheaper and faster to replace the nozzle rather than replacing the original nozzle+heaterblock. There are also stainless steel nozzles available for purchase which are more resistant to abrasion.
