Tevo / 2020 / 2040 E3D V6 X-Carriage + Hot End Assembly

I wanted to put an E3D knockoff on my Tevo tarantula so I designed an X-Carriage and cooling solution to accommodate it. Required HW: - 10 M3 Square Nuts - 1 M3 Hex Nut - 7 M3x10 Screws (I used hex-head Caps) - 2 M3X25 Screws - 2 M3X30 Screws The design is tolerant of larger screw lengths in most spots(+2-4mm will work in most cases) Suggest you use 4+ Walls on the X-carriage, mostly designed to print without supports but the "E3d_Fan_Duct_Longer" part requires them over the two screw mounts that jut to the sides and the "E3D_X-Carrage_B" part requires them to support the heat sink cavity. The Fan Bracket slides on from the side and is secured via an M3X10 and the hex nut. For the Heat Sink cooling fan I have pockets for Square nuts but have found you can just tap threads into the plastic and it works fine. I'm using this: https://www.thingiverse.com/thing:2582487 to mount a radial fan on the Heat Sink cooling fan mount (shown on one of the pics) 1/4/2020: Adding a wire retention piece to allow the heater and thermister wires to be constrained with a zip tie. Adding a modified fan duct that opens up the bottom fin on the heat sink for air flow and redirects more air flow from the top of the opening toward the bottom of the heat sink. Adding a 90 degree fan bracket as mine was interfering with some lights I have at the top of the frame.
