Unimog 6x6 with portals

[cooper_xl]

Well,have my mudguards printed and painted.Was waiting for the m2 torx bolts to mount everything

see the mounts below the tank?


Now it needs the metal mounts to the chassis and the fuel cap

the fuel tank you build is amazing, I have to build something similar for my custom Unimog project, I found these option at Shapeways but your design is better ;

[cooper_xl]

thanks!...I'll put everything on thingiverse soon if you are interested. that one on shapeways is pretty expensive

[cooper_xl]

Well, things are going slow...was anxious to get the metal stuff done to pass the bed to the lady who will do the tarp.











At first, I will only make the front and rear arch like the real ones but all my reference photos were from 4x4s. This long bed would need one more,atleast

The archs are 4mm stainless steel and the rest 3mm. The feet are steel, brazed to the archs.Was planning to braze everything but I'm quicker with the TIG.

That is some quality detail work there! This looks like an awesome build!

[cooper_xl]

One more random detail for the 'mog










I live in a rough neighbourhood



The tailgate is almost painted and ready to be mounted. Did one of the bench seat but maybe I'll put only one and left the space left for cargo

[cooper_xl]

Printed a pair of improved functional tailgate hinges to be glued to the bed. They're printed in one piece, let's hope they hold




Tailgate with the hooks. Not shown, are the rubber stops(printed in TPU because scale )




First look at the tarp

[cooper_xl]

Hi!

I'm on the final stretch of this bed.Just need to glue the planks of the seat and make the chassis mounts

Anyway, there's how it looks:



Closed latch





A printed hinge.





I'm very excited how it turned out.Anxious to get it on the trails

[cooper_xl]

Because the truck has to function properly,I've improved the rear shocks to handle the extra weight.

The old ones weren't shock absorbers at all, were pretty and scale but there was no o-rings on the shaft so they couldn't hold the oil.

So , found these 60mm shocks for cheap and took the springs out and filled with 1000 oil:





They only problem is that they are made for m2.5 hardware and couldn't find 4.8mm balls for m3 so did these ones:











Don't like them upside down but unfortunately,this was the only way to mount them...



Another detail that was buggin me was mounting this tow hitch






Got the hitch from eBay, some M2 scale bolts and printed the frame around it


Don't mind the rust. It's almost ready to be painted

[cooper_xl]

Well,in my opinion, 3D printing is cool but when we only print scale acessories, we're just scratching the surface of it's true potential

The Moose axles being released free maybe clicked in my brain and came back from an old idea of making a full axle for the unimog. The problem is that I like this truck but the ugly axles seem out of place. Adding to that the front axle is a Frankenstein that i don't know how it never failed

So,I've started to design from scratch,heavily influenced by the now discontinued SSD D60 axle housing.

This housing will have all the features of the old one like being 20mm narrower to compensate to portal boxes,panhard mount, spring perches,spherical ends, 7° of caster and 3rd link mount. The pumpkin is small as the stock gears allow...


Front:



back:











Diff cover will be designed next....

[cooper_xl]

Like the Stones said: "I see a red axle and I want it painted black"










more subtle...

[cooper_xl]

After more than a year without trails,finally did it!!

Took the JK, the M548 and the 'mog to drive a little. Ended driving the Unimog a lot more than the others














Tried an easy line with sucess and was doing slightly harder lines and the truck was doing great...ended in one that I was positive that will fail...but the truck managed to climb. In 1st gear of course

That's a very realistic-looking rig, incredible job...

Thanks!

That previous axle sparked an old idea of making 100% printed axles based on the real ones. About 4 years ago I worked on that, having housings printed but the big scx10 internals didn't allowed to do them small and nice. Fast forward to the present and adding to my improved 3d skills,we have more choice

Someone suggested TRX4 diff gears and using lockable diff. Was a great idea but the parts are too expensive.Remember that I need 4 sets to make 3 axles. Went to scx10.2 gears from Ebay and they seem good, nice machining and finish

The issue was doing the gear mesh because of the "high pinion" feature but after a few tries, is done

Doesn't seems but it works:


I'm aiming for this,2 halves:



The angle on the pinions is because torque tubes are a possibility. I'm just waiting for parts to arrive to confirm if it's possible

You have incredible skill in designing and 3d printing

Thank you! I'm still learning how to 3d model






just to keep this going:

My transfer case was a 2s Helios, nice case but big. Wasn't able to center it and adapting the torquetubes to it would be a PITA so, Plan B:







This transfer case has everything integrated and it's small as possible. Uses stock scx10 gears so is easy to repair. Could used smaller gears but the torquetube mounts will always be this size so there was no advantages





Here, everything mocked up with the v1 transfer case(above is the v2,not as tall)



This transfer case will bolt to a new skidplate that isn't ready.

[cooper_xl]

Did the skidplate and mount the transfer box as centered as I could. The torquetubes require that. The skidplate sits lower than the older one but I think that wouldn't be a problem, this is a scale truck afterall



Quick mockup:












Missed the torquetube length by a couple of milimeters but the real ones will be machined from aluminium so it's fine

The rear trackbar mounts are in place. Need to redo the motor mount and wait for the diff bearings to arrive. My plan is to complete and mount an axle before moving to the next one

Unimogs are the best, 6x6 even better!

x2 !




Hi!

Quite slow but I don't gave up on this. Even if it's harder than I thought....(so that's why few people try to do this...hmmmmm)


Still waiting for bearings and better filament to print the axles but in the meanwhile, did a new motor mount because the old one will interfere with the front torquetube. Speaking of torquetubes, started on the definitive ones, printed one at first to confirm the length and if everything worked.

So, now in aluminium:
