Ender 3 CR-10 Direct Drive BMG Bondtech Extruder E3D V6 and Volcano

This is a remix of Wundel's Ender 3 Direct Drive converion kit. It looks very promising, but there were 2 negative comments: Somebody missed a place to tie the cables, and other complained about tilting the 5015 fan in 45 degrees killed it very quickly. I also didn't like the part cooling, because it is only from one side. So I took my basic 3D design skills, and tweaked the models to solve these issues. I made a cable ziptie post, and new two-side cooling duct with an upstanding 5015 fan. I borrowed the fan duct nozzles from Acwest's beautiful Hero Me fan duct design. (Thank you!) On my variant I had to sacrifice the place of the bed leveling sensor. You need to attach the hotend cooling duct on the right side, blowing the air from right to left. The height of the part cooling fan is adjustable. I designed for V6 Volcano hotend, but it can be used with normal V6 also. In Wundel's original design, there is a 30mm clip on hotend cooling fan duct, and a 30 to 40mm fan adapter. I made a merged one from those, where the 30mm and 40mm ducts are merged together. I also use a 40mm fan guard (4HOLE.STL) from Prot0typ1cal.
