[MOC] Hummer H1 - Lego Technic 42177 Model B
eric trax posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The Hummer H1 is one of the most iconic vehicles ever created. I don't know if there is anyone who doesn't know this car, even though it premiered a long time ago. This vehicle has always been on my list to build, although at a very distant position. Thinking about another alternative to the 42177 set, I started to wonder if it is possible to build a Hummer from it. I managed to do it, although not without problems... The Hummer has a very characteristic design. The chassis is basically a frame, four wishbones and a V8 engine. The biggest challenge was building an independent suspension. The original set has a rigid axle at the back so I was missing one CV joint. However, I managed to build a custom one. I added a LOW/HIGH gearbox and a central diff lock. Due to the length of the wishbones and the two different diffs in the axles, it was not possible to make a rear axle lock. This is not a problem, because I wanted a realistic ground clearance of the vehicle, which is 6 studs. When building the V8 engine, I was inspired by the new Koenigsegg Jesko set. The design is very simple and compact but looks great. When I finished the chassis, it was time for the rest. The Hummer is quite large and I was worried whether I would have enough bricks to build the entire body. When I started building it a little after 8:00 PM, I got so caught up in it that I didn't take my eyes off the bricks until 5:30 AM the next day I already had a prototype of the body and I knew that there would be enough bricks. However, later I had to rebuild the sides of the vehicle. The prototype had angeled door pillars, but it turned out that they were problematic when opening the doors. The new version is much more solid and the doors open without any problem, and are additionally attached at the bottom and top.

[MOC] Mercedes Atego Expedition Camper - an 42175 B-model
Timorzelorzworz posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Thanks to the engaged forum user @R0Sch the inventory for the LEGO Technic Volvo Truck & EC230 Electric Excavator (Set 42175) was shared on a legal way two months before the official set release, so I was lucky to start a B-model design very early. No, I had no early access to the physical set like others and bought the set at day one, August the 1st. in my local store. The model I made is a Mercedes Atego Expedition Camper, only with parts from 42175 Volvo FMX Truck & EC230 Electric Excavator as alternative build (B-model). The main set provides all the parts to build, no spare parts or other parts outside this set are required. Designer love to put easter-eggs inside, isn't it? So this model uses exactly 2024 parts as an easter-egg for the release year. Pneumatic Functions foldable stairs to access living cabin lifting platform to carry Quad Functions & Features HoG-steering working piston engine openable doors for drivers cab pendular suspension with turntable openable door for living cab openable sidedoor to access equipment foldable sunroof twin tires in the rear cargo-area to store equipment many equipment included (read below) upgradeable with other wheels and MB-star (from 42177) measures (all closed) 40cm x 17cm x 19cm Model in Action Some Impressions Some Outdoor-Shots Cabin Details On top of the drivers cab you can grab a wheel to steer the truck with a pretty good steering angle. Both doors of the drivers cab can be opened to watch inside. Between the driver seats you can find a working 4-cylinder piston engine that is connected to the rear twin tires. The model comes with pendular suspension, using a turntable from the set between the drivers cab and the living cab with drivetrain through that turntable. The pendular angle is limited to approx 7.5 degrees per side. Pneumatic inside Like the 42175 main set, this alternate build has cool Pneumatic functions inside as well. The pump is controlled from the top of the living cab; the valves from the side. Basically the living cab is divided into 2 sections: At the first half all the Pneumatic stuff and the working stairs is placed. The second half provides enough space to safely store and transport all the equipment that comes with this model. Foldable stairs (Pneumatic) Once the door for the living cab has been opened, the stairs can be pumped down to fully reach the ground and to access the cab. The door closes even when the stairs is completely down, which is a pretty nice feature I'm happy with. Track links from the main set are used for the steps to make a solid staircase with some refreshing design never seen before. Lifting Platform (Pneumatic) The Mercedes Atego has a quad on his trip, that is carried by a lifting platform. When the Pneumatic cylinder is fully extended, the platform reaches exactly the ground and the quad can enter on this. Luckily the Pneumatic has enough pressure to lift up and to hold the whole platform with the weight of the quad. Additional chains can be used to secure the platform and the bike while driving around and going on vacation with this model. Sunroof In case it is getting hot inside the living cab, a sunroof is openable up to 30 degrees with a crank mechanism. This also provides more space over the head for people inside the living cab. When the sunroof is closed, it is completely hidden inside the frame of the Camper. Equipment included The mentioned quad with working steering Camping chairs & table... ...they are all foldable to stack Smoker BBQ-grill and fire-barrel... ...with openable lid for the grill Mobile satellite dish that fits on the table... ...and even better on top of the Camper ALL of the equipment can be transported with the Expedition Truck itself and nothing stays back during vacation. The equipment is accessible through a large openable sidedoor in the living cab. Borrow them a real star By design, it's very easy to spend the model a more realistic looking Mercedes-Benz star. Just pull out the axle with the 2x2 round tile with hole and replace them with a custom 2x2 round tile and pin with snap. The actually best match for a real star on this Atego is with the set 42177 Mercedes G-500. Either the 2x2 round tile with print or the one with sticker in the back can be used here for a Mercedes brotherhood. When the street is not enough... ...then give the Camper your own rims and offroad tires. By design, the model is made to easy swap wheels up to 56x26 Tractor tires with no rebuild required. Based on the real thing Front and drivers cab are highly based on second generation Mercedes-Benz Atego from 2013 with 4-cylinder diesel engine. Final note A Camper was on my personal B-model wishlist for a long time and now thanks to the inventory of the set 42175 it was possible to make it. A lot of summerlove was spent on this one and the whole model feels like endless vacation. Just pack some things and go on a trip for a long time. A heart-project I was working on from beginning of June to end of August this year. Have fun with this Mercedes Atego Expedition Camper alternate build.

[MOC] Unimog U423 - 42177 (G500) Model B
eric trax posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I won't try to make a big and epic introduction. Each of us knows that the first thought that comes to mind when you see the 42177 set is a Unimog I didn't think long about a specific model. I always wanted to build a Unimog U423 and the premiere of the Mercedes G500 was the best opportunity to do it :) When I got the set in my hands, I immediately started designing U423. The plans were ambitious and as the prototype developed, I added new functions to check how many bricks I would need. Finally, I used 2,513 elements, or about 87% of the Lego set. Ultimately, the model has 12 functions: - front and rear floating axle - central differential lock - rear axle differential lock - all-wheel drive - working dummy engine - front and rear PTO with two speeds - front hinge system - 2-way tipper - HOG control - liftable cabin - openable hood - openable doors Length 41cm x width 20cm x height 24cm / Weight 1620grams / Scale 1:13 When I was building the model, I really wanted people who would build their own Unimog to be able to modify it by adding their own tools. That's why the Unimog is equipped with a front linkage and drive shafts at the front and rear. You can easily add a snow plow, sand spreader or municipal mower to it. It seems to me that the model is an ideal base for everyone to create their favorite version of the Unimog, although even without modifications it is a lot of fun to play with! :D I'm not entirely satisfied with the fact that I didn't manage the iconic lights. I had probably 20 versions of the bumper and only the current one I liked enough to include it in the final model. Maybe I will add some modification to make it look better, but I will need a few system bricks Of course, the biggest thanks go to the designer of this set, @grohl. Thanks to him, after 2 years I bought the technic set again and it is definitely the best one in the last few years. Thank you!
