Soooo.....

First of all: Again thank you Blecheimer, the fan shroud is on the way to PLA :smile:

Second: I managed to get access to a solidworks station and started an (ugly) attempt to come closer to the thing I have in mind.

A few minutes ago I published a work in progress on Thingiverse but honestly I have no idea if it is printable...

    Hi,

    Made myself these 2 40mm fanducts for my dualextruder (Standard Umltimaker) printed in ABS.. the PLA ones only lasted 10 seconds :). Running around 30% gives enough flow. Better circulation around the print I guess,(Doing where they are made for) So 4 of your 25mm's are more than enough!... Guess you Might consider 1 on each side.

    40mm dual fanducts

     

    I do like the idea off that UM2 kind of Heatshield (I guess it is) under the heating blocks.

    But when I'm printing dual colors it gets pretty messy sometimes :(.

    Don't know what the UM2 users have experienced until now?, but I'm afraid of piles of burned Pla in between that shield.

    Or it should be very easily removed....

    Thank you for this hints - I think I will better try to cut my model out of sheet aluminium than print it in PLA :-)

    Regarding flow control I thought about using a resistor to reduce the flow on the right side fans so to have nearly equal conditions on both sides (left fan flow has more way to travel :-) )

    ok, was a nice weekend - I managed to cut & bend the fan duct - unfortunatley I had to use blue tape to get it sealed :-(

    here it is:

    testing will start soon but I´m looking for something comparable... any ideas?

    This is awesome, would love to try something similar. Let us know how it goes!

    Do you have the fans wired in parallel using the stock wiring? Or something else?

    I wired it directly to the stock wiring - just soldered it together to one plug... Hope that the current is not too much.

    Today I tried it on a simple piece so I have not testing data up to now.

    I will post it a.s.a.p. and generated a seperate topic here http://umforum.ultimaker.com/index.php?/topic/3446-um2-like-fand-duct-for-um1/

    where I will post my findings.

    I'm using blechmeimer's fanducts for the UM Original V1 Head and had them in PLA.

    Unfortunately the main issues are that:

    -After some use they bend

    -The part designed to fit in the head screws is quite weak (and seems to be also the spot where the fans start bending).

    Any chance to have a reinforced design to avoid bending on those screw holes?

    You can print this one I made, the original was based on blecheimer's design, but it's since evolved into a different beast. I've been printing with it for about a year now.

    This one has an extra screw slot on the bottom side to keep it tight just for the purpose that you mentioned. And clears the side block without issues. (I had some screw scrapage with blecheimer's initial design)

    It's for a V2 hot head though... not sure if it's compatible with V1

    Do you also have a right fan, or is the Blecheimer version ok for that one?

    I don't have a right fan, mine only has 1.
