After lot of requests, I’ve updated the E3D V5 hot end carriage to the E3D V6 Hot end. The hot end clamp is completely redesigned, but the baseplate and fan duct are the same. So if you upgrade from the V5, you only have to print the “cooler base” and “cooler door” This hot-end carriage makes the bowden tube E3D hot-end V6 ( http://e3d-online.com/ ) compatible with the Felix 3D printer (1.5 and up). It's designed for the felix Printer, but can easily be adjusted for other printers as well. Just fit it with two bolds against the rails. The hot-end can easily be removed by unscrewing 2 bolds and opening the door. It’s specifically design for the V6 version, The v5 or if a newer version comes up with a new layout cool-ribs, it will not fit. The cool ribs are printed inside the PLA clamp. If you need a V5 version: http://www.thingiverse.com/thing:159142 It uses 40mm fans (not the E3D supplied 30mm fan) More cooling, less noise. (and comes standard with the Felix printer) This is a two part design. The other part is the Bowden feeder: http://www.thingiverse.com/thing:159159 Here's a instructional video of the (V5) carriage and bowden feeder in use: http://www.youtube.com/watch?v=ZsNm0UfQsyQ Special thanks to Guillaume from Felix printers to supply the rail-base. If you use it, please share a picture!Print without support. The Cooler door has built in support in the arcs. It’s probably not necessary but the clamp is a tight fit, and the arc needs to be perfectly round. Without support it might sag. There’s also a support less version included. Use M4 bolds and nuts to fit together. (the bolds for the duct go through the arm.
