I finally got around to installing this duct and I've been having some issues.
The Duct consistently sits about 3mm lower than the nozzle. Wondering if anyone else has had this problem and/or come up with a solution. I might have to go for a different cooling duct design. So I'm open to suggestions about other ducts that are known to work.

i think you just need to push it in a bit ,it should click into place ,just hold the acrylic at the other side ,but dont put too much force so not to break the acrylic.
this fan duct helps a lot ,but it is only effective from the side its facing ,would be nice to get a duct to blow from all directions.

I think that was part of the problem, but I think the head is drooping in the Y direction. I've ordered some 10mm bearings to replace the 9mm one on the X runner.
Maybe my duct didn't print perfect and it won't push onto the acrylic spacer all the way.....or it's the Y droop.... or something else
I'll keep messing around with it to see if I can get it to work any better, but I might just go ahead and try and design a donut ring duct

The fan duct is here: [github.com]
(I need to add it to the list on the first page of the Ormerod 2 instructions: [reprappro.com] )
This has been tweaked fairly recently, as the acrylic fan spacer was changed, and the fan duct had to change too. So check you have the latest version.

Hmm... I wonder if we've managed to ship two different fan spacers with Ormerod. If one fits, I don't think the other one will. I'll try and remember to check tomorrow.
This is the earlier one: [github.com]
This is the current one: [github.com]

well, this newer revision of the duct fits much higher up and seems to work fine for me. I'll use in in an actual print later this week to see how well it works. This jointed dragon's head has been giving me a lot of trouble without cooling [www.thingiverse.com]
The OP didn't have anything about mounting the fan to the duct, but I drilled the duct holes out with a 2.5mm bit and M3 screws self tap into it. I think 30mm would be the right length, but I only had 40mm screws on hand I wound up cutting to length.
