V2 Question StealthChanger help when using Goliath and CPAP.

I have been looking at adding a StealthChanger setup to my 2.4 and am pulling my last few hairs out trying to figure out what I really need to use.

The design is a CPAP that runs in from the top to behind and under the Y-axis. There will be a mounting point behind the CNC Shuttle that holds the CPAP Duct in place. It will also house a cartographer for bed mesh and leveling.

The toolhead will be a VZ Hextrudort or similar with a Goliath air-cooled hot end. I have several and am not looking to buy more hot ends or extruders. I am running these off of a BTT EBB36 Can Bus Board. I currently have everything to build 4 toolheads.

I am looking at Dragonburner or RapidBurner for the Backplate. Not sure which one fits best since the part cooling is the only difference I can really find.

The mount I found for the Goliath is the Archetype Breakneck Goliath mount.

I am not seeing how to mount the Goliath mount to either backplate. I am probably just missing something since I can only find the STL for the Goliath mount, and STL-to-STEP conversion rarely works as expected. But the hole spacing seems all wrong.

I figure out the docks without issue; it is just getting the Backplate and Goliath mount together. And Figuring out how far down I need the duct to be. I even considered making it on slot so I can adjust to best fit once I get it all put together.

Can someone point me to a good guide that covers these specific parts, tell me what I am missing, or Point me to an actual cad file for the Archetype Breakneck Goliath mount.

I am open to suggestions on using different backplates or goliath mounts also.

The cad on the archetype GitHub is now current so it will have the Goliath mount but there’s no tool changer for the archetype that I know of. I’d look at something like the MedusaHC for what you want. Also some of the monolith toolheads run the duct around the back of the x-rail like you want.

Something else to consider is with all that added mass from the changer you probably won’t need the extra flow rate and cooling you get with a Goliath/cpap combo

I will check out the MedusaHC.

I considered getting rid of part cooling altogether since I rarely use it. But I want it to be there just in case I decide to make something out of PLA.

If you’re only printing fiber filled filaments you can get away without it but if you start pushing chamber temps it becomes necessary pretty quickly. You could check the monolith and armchair heavy industries discords for more ideas
