I’ll start this summary with credit where credit is due:

• Original design of E3D accessories by thed0ct0r
• Inspiration for my holder and clamp design by herrfrost

Background

About two years ago, I purchases an E3D V6 to improved the reliability of my Vertex K8400. Ever since I have been using the mount designed by herrfrost. However I found that the part-cooling fan really lacked, so wanted to add a Prisa-like duct. I found thed0ctr0r’s design, really liked it and decided to to adapt his parts to fit the K8400. The major difference is that I used a 3010 radial fan instead of the 5010, due to the lack of space. I also had to adapt the bottom piece of the XY-carriage clamps to fit the part-cooling fan duct.

Instructions

Required parts

• E3D v6 (lite)
• 3010 radial fan
• 2 x M3 screws 25 mm long
• 10 x M3 lock nuts
• 3 x 62 mm long M3 threaded rod
• 1 x 54 mm long M3 threaded rod

Printing

The XY-carriage is the only part that requires supports to be printed successfully. The part-cooling duct should be printed in ABS of PETG, not PLA, because of the heat surrounding the nozzle.

I used a layer height of 0.2mm and an infill of 40%.

Assembly

To fix the threaded rod, I glued the bottom lock nut with some CA-glue. This way, the excess rod protrudes above the carriage, not below where it could damage the build plate.

Printer changes

You will have to elongate the y-axis end-stop trigger as shown in one of the pictures. This is because of the extra width due the E3D v6. I have done this with a popsicle stick, but there are some 3D-printing alternatives out there.

The original bottom XY-carriage piece has to be replaced with a printed one, because it interfered with the fan duct.
