First tests of the new fanduck with protection on the heater against the airflow.
Still a work in progress:
- 40mm Fans
- Right duck is not at the good distance for now
- Air duck is centered on the nozzle
- Air flow shield is made with aluminum sheet (completely overrated )
A small example of the difference of with and without the shield. Without: the nozzle starts at 210C and after a few layers the nozzle could never exceed 200C because of the amount of air flow. With: the nozzle drop at 208C and goes back at 210C in a few seconds.
Edit: shield will pretty much stay this way

Hi,
now I printed the inner part again but now in the correct orientation as the STL file is.
First I made a mistake, I did not switch on the fan again, so here is what came out:
The detailed part look really horrible, the tips of the 'wings' turned to brown look like burned!
Then I enabled the fan (the outer part I printed with fan disabled) for the inner part again, here you can see the difference now:
The result is really great, amazing what UM2 can do!
The filament is Innofil3D ABS silver grey, it appears blue here since I used twho different light sources with different light temperature and my white balance is not correct here, so just ignore the color.
Then I inserted the inner part into the outer part, it fits perfectly - thanks Anders Olsson!
I tried to screw something and heard the click noise - wunderbar :wink:
BTW as you can see here even you have a faulty print, it never is useless. Learning by doing shows what went wrong and you learn from it making it better the next time!
