E3D V6 Dual Or Single Hotend Mount + Cooler For Velleman Vertex K8400

Make sure you keep the long side of the heatblock to the side. This set-up results in a build volume of 205 × 190 × 190, wich is larger than the original hotend set-up. You can use the mount for dual E3D hotends, Or in my case, use the side that isn't used for cooling the print.

I've used this X-carrier extender, and cut it shorter so it extends the carrier for about 5mm:

This prevents the hotend from bumping into the belt when homing the X-axis.
