How do you plan it mounting on spider?
Directly on lower part or with spacing in between(or another part)?
Consider having tubes at right angle to the spider, and than having tunnel to preferred spot. That way whole thing should be narrower and maybe bit lighter.

It'll be mounted upside-down. Won't be directly on the spider (though that's an idea to think about.) I'm just going to make a simple mount today, and then do something fancier if I think this style will work.

So far today:    Sorry for the blurriness on the last one. |

nice, just be sure you don´t have too much tension at home position.

This is the whole mechanism mounted. I just have it zip tied to the spider currently, and it keeps it at about the right position. Good enough to test with, I think.  I picked a bridge test from thingiverse and gave it a shot:    Not too bad. I will probably try different speeds, but not tonight. I also need to take this thing apart very soon and work on better leveling/calibration and check the diagonal rod lengths. Ryan |

Very nice! Is there much added weight? Are folks doing any sort of air flow / PSI test when they are testing these layer cooling devices?

It's not very heavy. I'll weigh it sometime when I take it off again.
I would like to do a smoke test or something to "see" the airflow. All I know is that it's blowing more than my last fan solution.

excelent result,
how long bridge could you do before?
now im even more fired to finish mine...

Has anyone ever thought of or tried a Vortex tube. I seen one used next to a furnace once for the electronics. Just air passing thru is at about 15PSI was amazing. The box was about 55 degrees F and the surrounding temp was way over 125 degrees F. they are very small and would almost cool to much if there is a such thing.

Googled to see what it is. Seems interesting but I'm not really sure how to apply it to a printer like this. Anyways, the air temperature isn't as important (as long as it's below ~ 100-120C maybe?) as getting the air to cool the filament just after it's been "placed" where it is to go. |

rick, as far as I know vortex tube needs a lot of pressure to work. more pressure, more temp diff. I saw this tech when I researched Tesla years ago..., it was tried to implement in auto industry (not by him  ), but got on banned/shut down as most of innovations... fast spreading open-source is the only way... |

Yeah it would cool way to much. Looked them back up and yes it would take like 90 PSI. And that would be a bad thing.  |
