Elegoo StealthBurner Mount

WIP: This model is still a work in progress.

Edit 1-7-23: I have redesigned the adapter using Fusion360 instead of Tinkercad and included the step CAD file. I have not yet printed the updated mount or tested it but it should work very well and is a little more polished than the original Tinkercad model which I have left an archived copy of up for use if you choose.

I remixed https://www.printables.com/model/139183-ender-3-v2-voron-stealthburner-conversion to work on the stock hotend carriage for the Elegoo Neptune 2 / 2S / 2D, may also work on the X though I'm not 100% sure if it uses the same carriage or not. I have not tested anything other than the fit to the carriage yet but everything “should” be the same as the original other than the carriage mounting hole locations. Pictures are from the last iteration and the slight interference on the head of the v-roller bolt heads has been addressed. You will also need to remove the washer from the lower v-roller bolt to get it to sit flush, it appears to be unnecessary as mine operates just fine without it. 

You will need to get the single bowden adapter, etc from the original model if you want to utilize it. I have included the modified dual bowden adapter for the 2D. You will need to get some bowden collets like these: https://www.amazon.com/dp/B092ZGBC1M the thread in PC4-M10 /M6 will not work. You will also need heat sets and bolts. This adapter only works with Bowden setup and not CW2 direct drive, I do have a separate model that replaces the entire X carriage that is compatible with CW2 though so look at my other models if you want to go that route.

I have added a BLTouch mount that utilizes the stock probe mounting holes on the Neptune to get further away from the hotend as there have been reports of heat damage to probes from the Voron community when utilizing a BLTouch style probe behind the hotend, which is were the original adapter setup places it. 

You will lose 24mm of build volume on the Y axis due to the nozzle sticking out further forward than the stock hotend and 1mm on the X. You can set the X_MIN_POS to -1 and the Y_MIN_POS to -24 and the bed size to  234 on X and 211 on Y and then you won't run into issues with it trying to print off the edge of the build plate, you should also change them in the slicer to match. The probe offset is 51, 17, 0. With my individual setup with the E3D Revo Voron hotend the z-offset is -0.81 but that will be different for you probably especially if you are using a different hotend.

All of the different official toolhead mounts are on the SB github. https://github.com/VoronDesign/Voron-Stealthburner

If you want to use the stock MK8 hotend that comes with the Neptune 2 / 2S this should work, though I haven't tested it myself: https://www.printables.com/model/137768-voron-stealthburner-mk8-toolhead

I also have a modified StealhBurner cover based off the beta7 stl that replaces the Voron logo with the Elegoo logo and a matching diffuser that I will be posting separately for those who are interested. https://www.printables.com/model/185503-elegoo-stealthburner
