x carriage fan duct for E3D-V6 Recently I read the post of NopHeadt: A bridge too far about printing the fan duct for the E3D hot end. He concluded that Slic3r gives the better slicing for this part in particular. Nevertheless I have been using Skeinforge for a while and I prefer it by its accuracy. The printed x carriage fan duct can be seen in the attached pictures. It was good, despite a little error filling in 2 layers the holes where the screws are inserted. In the pictures can be observed too, the bridge is almost perfect in the sense that there is no a hanging thread. The main parameters that I used are: Infill Begin Rotation to 0 degrees and Infill odd Layer Extra Rotation to 0 too. I now that this values decrease the mechanical resistance of the part, but in this case, the fan duct is not under load or under a fluctuating load. https://reprap.org/forum/read.php?292,646610,646610#msg-646610 Fri, 10 Jul 2026 19:02:02 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?292,646610,659719#msg-659719 Re: x carriage fan duct for E3D-V6 https://reprap.org/forum/read.php?292,646610,659719#msg-659719

Looks like you are trying to fit the parts for the sturdy version to a dibond machine.

Ouch! You are right. Thanks.]]> demetris Mendel90 Tue, 03 May 2016 08:04:58 -0400 https://reprap.org/forum/read.php?292,646610,659254#msg-659254 Re: x carriage fan duct for E3D-V6 https://reprap.org/forum/read.php?292,646610,659254#msg-659254
The assembly looks like this:

@nophead: The distance between the bracket mounting slots seems much smaller than it should and does not fit my printer (bought it March 2013). Is there another version of the x-axis carriage? Also, how do you orient the e3d hotend in order to fit the duct?

Thanks.]]> demetris Mendel90 Mon, 02 May 2016 04:40:48 -0400 https://reprap.org/forum/read.php?292,646610,659201#msg-659201 Re: x carriage fan duct for E3D-V6 https://reprap.org/forum/read.php?292,646610,659201#msg-659201

I am currently printing this, so I could update you on the results once finished.]]> demetris Mendel90 Mon, 02 May 2016 01:47:12 -0400 https://reprap.org/forum/read.php?292,646610,646902#msg-646902 Re: x carriage fan duct for E3D-V6 https://reprap.org/forum/read.php?292,646610,646902#msg-646902 nophead Mendel90 Thu, 31 Mar 2016 14:51:17 -0400 https://reprap.org/forum/read.php?292,646610,646787#msg-646787 Re: x carriage fan duct for E3D-V6 https://reprap.org/forum/read.php?292,646610,646787#msg-646787 You are right respect to the bridges over the holes. The same feature is present in the Wades block, right?]]> wgaona Mendel90 Thu, 31 Mar 2016 09:44:38 -0400 https://reprap.org/forum/read.php?292,646610,646660#msg-646660 Re: x carriage fan duct for E3D-V6 https://reprap.org/forum/read.php?292,646610,646660#msg-646660
The bridges over the holes are deliberate. That is where it transitions from a hex nut trap to a round hole, so the outline of the hole would be printed in mid air without the support membrane. I drilled them out for the kits. If I was designing it again I would probably use this technique but it is very slicer setting dependent.]]> nophead Mendel90 Thu, 31 Mar 2016 03:54:54 -0400 https://reprap.org/forum/read.php?292,646610,646610#msg-646610 x carriage fan duct for E3D-V6 https://reprap.org/forum/read.php?292,646610,646610#msg-646610 A bridge too far about printing the fan duct for the E3D hot end.
