As any Ultimaker 2 owners know recently Ultimaker has been talking about the Olsson Block addition to the machine. So I decided with all this news about it why not do a video about it and also document how I change my nozzles out in the process. Hope this helps anyone out there with an UM2 and is debating getting an Olsson Block for it or debating picking up an Ultimaker 2 during the current promotion time!

Thanks! With all the recent talk I thought it was fitting and even though install can be slightly tricky, being it is a one-time deal, it is well worth it :-)! Especially for people who do a LOT of printing and also people who print lots of nasty materials (me!)
Thanks!
It is worth considering, also when you keep in mind that the nozzles are capable of being swapped out so you can go from a tiny nozzle > big one pretty fast!
Thanks for sharing 
I agree with you that the Olsson Block is a must have if you print abrasive materials like carbon fill or even glowfill (i weared down my stock nozzle with glowfill very fast). But i must say it’s also usefull if you print less exotic stuff, for example if you print PLA and ABS, just use one nozzle for PLA and one other for ABS. This will prevent clogs if you still have some ABS in the nozzle and print PLA after with much lower temperatures.
Also printing with Wood filaments with a 0.40mm nozzle is hard, try it with the bigger nozzles and you’ll see how easy it is!
One last thing, to change the nozzle you can also print the torque wrench that you can use with the tools provided with the olsson block, this will prevent from overtightening.
You can find the torque wrench here:

For me it’s the best upgrade you can have on the Ultimaker 2
@victorp might be a cool addition to our UM2!
I’ve debated printing the torque wrench just to have. I may machine my own fancier insulated handle wrench so I don’t burn my fingers every time I change nozzles! I’ve debated switching to a .6 nozzle so I can keep good details that a fine nozzle does but also get thick walls fast with minimal effort and things like woodfill can print way easier. That said my .4 proto pasta/microswiss nozzle is amazing.
