Easythreed X1/X2/X3/X4 upgrade to Nema17 and E3D V6 hot end

thingiverse

This is an upgrade kit for the Easythreed X4 model (but should work on any X's model - X1/X2/X3/X4). The upgrades include brackets/supports to replace the original stepper motors by Nema 17 ones and also a support for the E3D V6 hot end. For the Y and X axis, I'd recommend using Nema17 model 17hs4023 ("pancake" steppers). For the Z axis, 17hs4401 is advised, once pancake motors could not handle the axis weight. The brackets are pretty much plug-n-play, but the Y bracket needs that you drill 2x holes on the printer original structure, a longer belt is needed as well (3mm belts can be easily found in Aliexpress/Banggood). The Z-axis bracket is the trickiest one: I could print it without any supports, and the nuts go inside the "smooth rod" holes (M3 screws are then used to fix the smooth rods in place). When upgrading to the E3D V6 hot end, it is strongly recommended to also replace the original power supply, otherwise the printer won't be able to "feed" the hot end power demand. I've replaced mine with a 12V/20A power supply. The hot end is attached to the original printer carriage. You can also "salvage" the original 25mm fans and use them as part cooling fans, you can use 2x fans or just a single one. I've uploaded two files for you to choose (you need to use "e3d_v6_holder_cap_x4_with_tab.stl" to attach the fan funnels) The assemblies use generic M3 screws and nuts. I recommend printing the parts with Brim enabled, because they tend to warp.
