Ultimaker Olsson Block Kit for use with Ultimaker 2, Ultimaker 2+

The Ultimaker allows for quick and easy nozzle changes, so different nozzle sizes can be selected to suit each project. A larger nozzle is suitable for faster printing, while a smaller nozzle can be used to create more detailed prints.
Note:
Use of a torque wrench with the socket is not required but highly recommended to install nozzles without over-tightening. If a torque wrench is available for use with the socket during installation, please set it to a force between 1 and 1.5Nm. Take care not to set the force higher than 2Nm, as the nozzle could break off inside the block.
