Change the nozzles of your Ultimaker 3 with this simple tool

[DidierKlein 729]

Hi all,

Just a small topic about a design i made to change the nozzles on the hardcore by 3DSolex.

If you don't know what the hardcore is please check this topic that @UltiArjan did about it.

So i have been trying the hardcore for about a week now and i'm very satisfied about it, altough changing nozzles is a bit more complicated than on the Ultimaker 2+ because of the way the core is designed.

Basically you need to take the core out of the printer in order to change the nozzle and hold the block with a provided tool (or anything else) and make sure not to put any torque on anything else than the block.

So i designed this small tool in which you insert the provided metal tool. You just slide the core inside upside down and make sure it's well in place, then you can change your nozzle easily.

I printed my version in platec so i can basically also do it with the block still hot as it resists up to 120°c. There's also a dual version for fun

How i use it:

- Remove the filament.

- Do a cold pull

- After a cold pull shut down the printer and take the core out

- Place it in the tool

- Change the nozzle

- Put the core back

Make sure that your Z Offset is still good (easy to calibrate)

And done!

Feel free to give your thoughts or advise on some changes. I can also provide step of Fusion 360 files if you want to play with it.

Very Nice

It looks very nice indeed!

I do have some doubt on changing nozzles while the block is cold, I much prefer to do it while the block is hot. I'm working on something myself to heat up the core outside of the printer. This solution will for sure not look as nice as your design

Yes i agree you can still put it in this device when it's fairly hot (not 200°c)

Hi! That looks cool! What nozzle do you recommend for replacement? Do ultimaker 2+ nozzels fit?

No, they don't (too long). You have to use the hardcore nozzles from 3DSolex together with the Hardcore.
