Decals, man!!!
Don't think so. I tried and it's harder than it looks. I would need to study a lot more photoshop or gimp to be able to pull it off and in all honesty, I don't have the time. I hope that someone that will buy the files to 3D print will come up with decals that I could then add to the Jeep.
Today is the day! The 1/6 is finally completed. I will print a 1/8 in the upcoming weeks. I'll come and post the results then. In the meantime here are the 1/6 pictures.

Thank you all for your amazing support and friendship. It's truly appreciated!
In my opinion, decals aren't needed. A basic invasion star on the hood would be as far as I would want to go. If you were to put a USA along with a registration number of random numbers on the hood, then you would open yourself up to people wanting to fact checkers and grief. It would then snowball to the Army guys will gripe if you put the Marines on there, and the Navy guys will want the whole Jeep grey, then the Air Force/Army Air Corps guys will want a blue Jeep. Keep it simple, and people will take it for what it is, a piece of art.
Well done! It looks great!
Bravo!!! Thank you for sharing the final build! Perfect.
What a great project! Thanks for bringing us along.
Truly AMAZING bluesblooded!!!!!
Thank you Guys!
Just wanted to let you know that the 1/8 scale is coming along as well. Should have something to show within a week.
I've put the files on sale a week ago. There is approximately 25 persons printing the MB as I write this.
I'm also going to try to convert the 1/6 scale to make it RC. The virtual Willys MB project ain't over!
Ride on bb! Keep it coming.
Looks very nice!
Thank you bmorgil and okiemark!
Well the RC model will see the light of day.
Today I received my hardware.

One of my main goal is to keep the overall appearance intact. Therefore I decided to design my own transmission instead of using an off the shelf one.
Attachment 7425 Attachment 7426 Attachment 7427
I will sell my 1/10 and 1/8 model to make some room and raise some money to pay for the RC conversion. If someone is interested, please send me a PM.
Part deaux? Can't wait!
Thanks, I'm glad you are in for the ride.
the 1/8 is now completed. Here are some pics of the whole family

Attachment 7450 Attachment 7451 Attachment 7452 Attachment 7453
I'm selling the 1/10 for 125$ and the 1/8 for 150$ including shipping in Canada and US.
Will put them on Etsy later this week. For you guys, I'll give you 25$ rebate if you are interested.

Hi Bluesblooded,
Here are a few pictures from my GPW if it helps.
Bonne soirée mon ami
Stéphane de Ste-Thérèse
Just plain cool bb! It would be awesome to meet up with Stéphane. It is pretty neat when you bump into another forum friend. Your project turned out fantastic!
Hi Bluesblooded,
I would be verry happy the take you on a ride.
I should be ready in mid summer.
Keep in touch
Stéphane
I'm impressed! :o
Thanks AJ-MJ
A knowledgeable person told me that my original gearbox design was going to be a problem. The gear reduction was inadequate. With my configuration, the Willys would've run at 30mph.
He was very helpful and provide me with a fantastic spreadsheet to compute the gear stages and reduction. He said my goal should be between 3 and 5 mph.
I also need to build the gearbox in such a way that it will fit in the avalaible space without moding the visible parts of the Jeep.
So I came up with this gear arrangement.
Attachment 7469 Attachment 7470 Attachment 7472
Here's a sliced view which shows I have enough room to build a housing around the gear that will fit inside.
Attachment 7471
With this new arrangement in conjunction with a 55T motor and a differential gear set up of 13 teeth /26 teeth, the Willys at full throttle will run at 4mph with 110mm tires.
That is the only thing that will clash, the tires will have nothing in common with the original. I have not found RC tires that mimics the Willys tire look.
35 mph?!? Too fast! Too fast! Once you dial in your speed, remember that this thing is supposed to go the same "slow" fast uphill, downhill, underwater, over rocks, in mud, and the same fast driving in what you up there call real snow... Torque and traction and weight balancing, baby, so it does the same thing in all conditions! It is 4wheel drive, right? (So glad you are back at this)
bb.... so it's got Ludicrous mode? It is quite possible their are a few who will aspire to that!
Slow is good, I have to walk by it. Not planning to build a F1. And yes we have real snow here, so 4x4 is a must. I envy your dry hot weather. Still two and half months before it's all melted. So is Cindy home yet?
Maybe, but I doubt it will go fast very long. Everything being plastic, I bet the gears won't sustain the heat very long. We will end up with gearbox pudding.
Ludicrous mode. A must! No, she's been all stop due to pandemic. They should be back to it momentarily.
Hopefully she'll be home soon!
Worked on the gearbox housing. Will print and test in the next couple of days.

Now that's just gorgeous!
Might be this week! Hey, so last time you had to futz with the material. What are challenges with materials for gears?!?
Thanks bmorgil, it does look great in chrome.
The main problem is toughness and heat resistance. There is some material that are most suited for this.
Here's a table of different material with their characteristic.

So the best filament would be Polycarbonate. I myself will start with PLA. The strength is probably sufficient. The problem will be the heat. But I personally do not plan to run the Willys that long. I think it will be all right. But an RC enthusiast would be better served with Polycarbonate.
Making some adjustments to the current designs.
The bearing would not fit due to the required supports for printing. So I added a recess so the bearing fits.
Attachment 7487
Here is what the wrong versions looks like. The case will not close without scraping the inside of the bearing recess. Other than that it is functional.
Attachment 7488 Attachment 7490
My original design was to install the gearbox inside the frame. That would prove to be a problem if the gearbox breaks. It would require a total dismantle to get it out. I created brackets in the frame that the gearbox will sit on. This way I will be able to remove screws from underneath the car and slide the gearbox out of the hood.
Attachment 7491
This is unbelievable man. So great. Well, one day soon we will all see the all electric Willy's!
If I could only print one at full scale!
Here's the completed gearbox

I had a hard time to design the bevel gear for the rear axle. Gears are way more complicated than I anticipated. Fortunately for me, someone developed an add-on program for my CAD that designs Bevel gears with provided parameters. That was money really well spent.
Here we have the beginning of a functional rear axle. Now I need to attach it to the frame.
Attachment 7626 Attachment 7627
Now you have my serious attention. A functional bevel gear rear axle is moving into the future man!
For me it was the biggest hurdle. Designing bevel gear is way beyond my understanding. I was stuck on this part for two weeks with no solution in sight. I'm very happy to have found a program that did them for me. They are working really nice and smooth. Now I'm all excited to get this thing moving. It will have my total attention these upcoming weeks.
My attention reverts to materials. Lots of torque flowing through those itty bitty splines. Plastic? C'mon, man. Dip em in some metal!!!
I agree, they will break. Nothing can be done about that but to buy all metal axles and transfer case. I don't know why but there seems to be a lot of enthusiast that still don't mind reprinting parts as they break them. As for me I see this as another learning experience. My design is inspired by the 3DSETS axle gear design of the Landy I showed a couple of times. They improved upon this design by replacing the single pinion/drive gears by double pinion/gears. I will look into it if it breaks too easily.
Just remember, from an Application Engineering standpoint the gear train needs to be able to handle the maximum torque you can apply, and the horsepower you will apply for a length of time. In other words, how well your gears perform depends on the power you are going to ask them to transmit. so if you are using a big gear reduction it wont take a lot of power. Just remember each time you increase the gear ratio multiplication, the torque goes up equally on the other side of the gear reduction.
Thanks bmorgil, I will keep this in mind. So if I understand well, if my actual setup (pinion 10T, Drive 20T) is too fragile, I could make it tougher by increasing the Pinion number of teeth? For example pinion 15T, Drive 20T. But this will also impact the top speed as it should go faster with a smaller reduction ratio right?
Correct BB. No free lunch! For every action there is an equal and opposite reaction. However... If you don't have the horsepower to go faster, it wont. So the final effect of "under-powering" for reliability is a longer lasting slower accelerating vehicle.
We must stop now or we will uncover the deep secret of why "Hot Rodders" can't keep their hands off of things and just have to find out if it will go faster and what will break next.
