Seckit SK-GO2
Voron 2.4 Afterburner Hotend Adaptation
If you're looking for 100% forward compatibility with the Voron Afterburner hotend, you may want to look elsewhere.
Words
This is a simple modification to the VORON Afterburner Hotend Extruder Backplate to mount on to a Seckit SK-GO^2 Printer. I'm not going to rewrite their clear and short documentation, but I will be including my notes where we start to stray away.
I extended the Extruder Backplate down enough so that you can install some threaded inserts where the hotend component would lock into the Afterburner's mounting system. This is also reused for a simple BLTouch mount that's directly behind the nozzle.
Unless you have access to a large array of any size M3 Bolts, prepare to cut/grind a bunch to some reasonably specific lengths. Some of the bolts go in the opposite direction as originally designed, and others are shorter/longer.
What Parts to Print
You should only need one of each component I've included in this thing. I remixed this from their step files which don't match their released beta STL's. I believe that I grabbed their latest alpha modifications to the hot end, but there's no guarantee of forward compatibility. So you will need to print everything from this thing, and I don't recommend trying to mix and match parts from their github.
NOTE: If you don't want to print the 24.6 mm spacers, print the BLTouch mount small stl instead. I have a slightly oversized pancake stepper, so I needed to add a little bit of extra space between the X Carriage Plates from the SK-GO.

You can ignore anything before Page 24
Page 25 - No need to install the long, or short threaded insert into Extruder Cover that faces towards the extruder backplate
DO install the two short threaded inserts that face outward toward the Cooling Fan
Page 28 - Put an M3 Washer as a spacer between the Guidler and the Extruder CoverI believe they are missing a step, but you need an M3 bolt to anchor the guilder and you do install the threaded insert into the Extruder Backplate, so put that in when you install the Extruder Cover
Install two 32mm M3 Bolts through the top two holes of the Extruder Cover
The Extruder Backplate, Extruder Cover, and Guilder should all be installed at this point
Page 30 - You're going to have to get the whole cooling assembly installed kind of in one go. You're only going to use the bottom two holes to mount this onto the Extruder Front Cover.
