Complete redraw of the UQCT by Dbach_MetalWorks with 40mm fan mount and more air ducts. and more clearance for my j-head setup.
Ran a simple flow analysis in solidworks, but not tested in practice yet!
Have the parts printed and will post updates when installed.
Update! 11.1.2015 got the first set installed and noticed apoblem with mounting the fans and a minor problem with the lip designed to align fan-mount to shroud not printing well.
Also noticed that the fans cant run more than 40% speeds when close to printbed on my setup, without cooling the hotend too much.
The amount of air is a bit overkill on full speed but makes for some awesome bridges :D
