Anyone else had the problem that the holder is crashing into the screws of the end stop? It's just by the fraction of a mm, but it is still happening.

So far I have seen cases where there was to much space between the holder and the end stop but you're the first to tell me about there not being enough space, thank you! :)
As I mentioned in a previous comment, next week I'll be home again and I will upload the source file so anyone can change the length according to their prefferences using Solidworks. I'd be glad to upload an STL file for you with the correct size in case you are not able to open solidworks parts.
In the meantime you might be able to fix the problem using a file or rasp. Since the area of collision is very small, printing the part with a slightly increased dimension might fix it as well.

Since I read that you used PLA while I am printing ABS, a slight increase in dimension might actually really solve all my problems. I'll report back ;-)

My fan has some stupid thing on one side, which makes it fit quite badly into this mount. Could you please upload the source file, so I can add space for my fans special needs?

Hi Nitek,
Thank you for your reply. I will upload the solidworks file when I'm home in about a week.
In the meantime you could try use cutters to snip off the thin front of the mount and see if it still has enough strength to hold your fan.
please let me know if you need a different file type then a solidworks part.

Thank you! I'll try to use a rasp, but I am currently trying to get a bit into 3d modelling so this seems like a good exercise ;-)

I have just uploaded the solidworks part and the step file.
As I mention in the description, this part was modeled very early on so it is quite unorganized.

Turning the single screw hole into a slot will allow height adjustments for different hotend heights, as they can happen with different lengthes of the heatbreak - so very subjectively.

You are absolutely right!
I considered doing so but chose not to because you would need to tighten the screw a lot more to keep it in place when printing at high speeds.
The screwthreads inside the x carriage are unfortunately easily busted and to avoid doing so, I measured this part to match the height of my printer with mentioned cooler duct. Luckily, the heatbreak can be secured at different heights so this might be a way to optimise your printer.

I currently am looking into a way to make this part usefull to a wider range of makers while avoiding any damage to the x carriage, all suggestions are welcome!

Thanks for this design.
Could you give a link to the radial fan you bought ?

The radial fan i bought is a 12V 50mm fan from ebay: http://www.ebay.com/itm/252477139461

I have this printer too, no heated bed...did you print the fan mounts of out pla?...have they melted?

Yes they are made of PLA, k-camel pla from gearbest to be precise.
I was worried about melting as well but the distance to the hotend seems to be just big enough, so far I have not seen any melting or warping of parts. A note to add to this is that I have not made prints that took over 2 hour since I added this upgrade.
If any melting would occur, that would probably happen to the 360 degree fanduct or the body of the supercooler since those are closest to the heat. if that were to happen during longer prints you could always increase the distance between the hotend and the passive cooler a bit or print a larger fanduct. The part moddeled here would still be usable to attach the fanduct to.

edit: I use a temperature of 205 degrees to print

Nice design!
I've never tried a blower nozzle like that, but I'm definitely going to print this out

Thanks! please let me know how you liked it! :)
