I finally have my 2024 F350 King Ranch so time to start with the additions. I needed the 8' bed so it is not a Tremor, but this forum has a LOT more usable information than other Super Duty forums so this is the place!

Already done:

Igla immobilizer installed
Passenger side auto hub on in place of the fixed hub
Line-X is done
Undercover Armor Flex Tonneau Bed cover
Built Right bed molle panels
Built Right drivers side rear seat release
Front windows tinted
2WD valance

To do:
VIAIR on-board air (VIAIR 485c dual system
Carli 3.5" Pintop
Full stereo system

So here is what I am doing for the on-board air...

So @Whyte Rhyno has a really good write up on his install of the same system on a 2020 F250 Tremor which is what I am taking a lot of my inspiration from. With that being said once I dropped the spare tire there were immediately some issues apparent, namely a huge wire harness that runs on the driver's side frame rail which is not going to be easily re-located, there simply is not enough slack. There is also a module (no clue what it is) on the passenger side rail, but I already have a plan to move it which shouldn't be difficult at all.

So here is what I am working with...

Driver's side:

First item that I am going to tackle is what to do about the driver's side to mount that compressor (will be one on each frame rail on either side of the spare tire mount). I am using brackets that are made by VIAIR which are designed to hold the compressors.

Bracket:

With compressor:

The way I have decided to tackle this is to 3D print a spacer which will go over and encapsulate the wire harness on the driver's side frame rail. To design this spacer I am using a 3D scanner, specifically a Revopoint POP 3. Now, in full disclosure today is the first time I have even played with the scanner.... I ordered it on a Black Friday deal while I was still deployed in Iraq just to use for projects like this. I just got home 4/1/24 (am posting this 4/5/24) and today was the unboxing so to speak. I watched several videos while deployed and then watched a few more this morning, and basically put it to work scanning the wire harness/frame rail area. From watching videos on YouTube I already knew that trying to scan a black harness, on a black frame, under the truck and in shadows would be "challenging" and it was. The scanners use lights and a series of cameras to scan, since black absorbs light they are particularly challenged when scanning black objects, and even more so in poor lighting conditions... all of which I was fighting. But I knew this and had a solution. Revopoint makes a white powder like spray that comes in a can, when sprayed on something it looks like white foot powder spray (Tinactin), and just like foot powder spray it eventually evaporates. In this case it evaporates in about 20 minutes leaving absolutely zero residue behind. It is not cheap, but it sure did work!

Scanner:


Spray:


So after using the 3D scanning spray I completed my scan. There are some areas that did not scan due to the tight quarters and not being able to move around to all angles, but I got enough to work with.

I then imported the Mesh STL file into Fusion 360 to work off of start my design.

20240405_152529.webp


Once I had the Mesh in Fusion 360, and finally figured out to make the origin plane in Fusion 360 match the orientation of the frame rail (when I first imported it was waaayyyy off, needs to match to begin your first sketches), I was able to go to work. The first order of business was to verify dimensions, I did this by sketching the rectangular opening in the frame rail utilizing the Mesh file, designing a small part that was to fit inside of the rectangle snuggly, and doing a test print out of an inexpensive test material. For the first test print I used PLA, for the actual part I will use ASA as it is strong, chemical resistant and heat resistant... basically an evolution of ABS plastic. PLA is super cheap to print so for mock-ups and test prints it is the material to use, but not suitable for automotive use at all. Bottom line up front, it fit perfectly, like snapped into place.

The scanner appears to be dimensionally accurate which is certainly a plus lol, so next step was to design the spacer. I started by working off of the same mesh file and just building, sketching, extruding, blah-blah... basically just working in Fusion 360. Speaking of Fusion 360, I had never messed with it before either, started playing with the CAD program while I was deployed. That is the real learning curve, learning how to translate what is in your head to the program, learning how to manipulate it. I am in NO way an expert at it, but I am getting to where I can putz around enough to create what I need. I ordered a Qidi X-Max 3 enclosed printer at the same time as the scanner knowing that I would need one to work with the other, doesn't do much good to scan and design something if you cannot then make it right? I have been playing with it the past few days and am starting to get along with it, the X-Max 3 is a large(ish) enclosed 3D printer which is needed to print out of the higher temperature filaments that are suitable for automotive use. The more I use it the more things I start to think of that I can just make now.

Here is what I have come up with for the spacer. It will be made out of ASA as stated earlier, but for added strength (and since the spacer will be in compression) I am installing these 1.5" x 0.625" steel sleeves in the spacer where the bolts go through from the bracket to the frame. This will put the compression on the sleeves instead of just the spacer.

And here is the design for the spacer that is currently being printed, first print from PLA to verify fitment.

As stated, the prototype is printing now.

This is where I am right now, even with a 3D printer as fast as the X-Max 3 is it still takes a while to print something like this. I will test fit it tomorrow and make any adjustments, once refined (if it needs to be refined) I will do the final print and get to work on mounting the drivers side compressor. I will then get the passenger side compressor mounted which should be substantially easier, then the tank and on to the wiring. I will get into that later but the wiring is somewhat intricate as well since I will be running 0ga as it will be feeding both the on-board air and the stereo which is a whole other subject haha. The on-board air will also have an electronically actuated valve to purge the tank as necessary, and the on-board air will also be used for the Full Travel airbag system. I will update on here as the install progresses.
 
I am super impressed with what you did. I always thought about getting a 3D printer and scanner, but man - this is intimidating lol
 
Ok, time for an update.

Ends up being about .25" space from the air hose where it turns 90 degrees to the stiffener on the bottom of the bed which is plenty.

For the passenger side I made a plate out of 1/4" HDPE plastic sheet and mounted the module which had been on the passenger side frame rail to the back of the plate. I test fit the plate and then went back and routed the edges of the plate with a 1/4" curved bit just to make sure the edges would not chafe a wire, worked out well.

From there I ran a hose for each compressors air filter up behind each tail light to keep them out of the dust. I figured it will stay pretty clean there. Hard to tell from the pictures but they are very secure in that cavity.

Very impressive my friend, thanks for sharing the progress!

It really isn't too bad once you start to mess with it some and understand how it all works. I am of course still learning, but starting to get the hang of it.

Thanks, I think it will be pretty slick once done. My main objective is to install it in such a way that hopefully I never have to touch it again. Would like to try to keep it as factory and trouble free as possible.

Right on, I did the ARB twin above the spare tire and it has worked great for me. Love the time and energy you put into your mount. Well done!

This is so awesome. Love your thinking and the process. Designing and printing stuff is so cool.
 
I have been meaning to update this thread, might as well get to it now. So I have the onboard air system installed and everything is up and running. I will admit to having chased down several leaks at fittings, but that has all been done and it holds pretty well. The air will leak down over the course of about 3-4 days eventually, but with as many fittings as I have (kind of a lot) that is not surprising. I am not worried about this however as I do not leave the system pressurized if I am not using it so no worries to me.

Here are some of the pictures.

Distribution box with the relay for the compressors and the air solenoid to dump the pressure from the tank. I 3D printed the box using ASA and the solenoid is hooked up to an upfitter switch as I really have no want to climb under the truck any time I need to purge the tank... It works perfectly and the air solenoid was all of $45.

20240427_140400[1].webp


I installed a pressure regulator and two air fittings on BuiltRight Molle panels

20240428_185246[1].webp


I then ran another air line through the drivers side frame rail (which was a PIA) and put another air fitting under the front bumper behind the air dam. I figure this way I will have access to air from the front or back of the truck, just a little more flexibility.

20240428_185633[1].webp


One of the reasons for the onboard air is to support the Full Travel airbag system. It is being controlled with a PacBrake wireless airspring controller that bluetooths to my phone. Seems to work well.

20240425_194412[1].webp


The Full Travel system utilizes removable spacers that allow for articulation and a better ride when the airbags are not needed, they slide onto the perches that are mounted on top of the leaf pack. Seeing as how I did not want the perches loose in the truck I made some measurements and replicated the mounting plates that the perches attach too. I then recreated the perch in Fusion 360 and merged them into a mount that worked with the BuiltRight molle panels. They slide right on, are out of the way, yet easily accessible when needed.

So at this point the air system is good, and the truck is coming along. I have also installed a pretty intricate stereo system (if you think the air system looks like it was a lot of work....) and most of the exterior is done. I still have a few more plans for it, but happy with where I am right now.
