3D Sets Mini Truck: Rocky Dumper

3D Sets Mini Truck: Rocky Dumper 1.0.1


Introducing one of two new models, the Rocky & Roady trucks. Both models are suitable for enthusiasts of all ages, including adults and children. Their simple yet advanced design makes them ideal for promoting quality family time while building RC models together.

Importantly, they can carry a real load, making them all the more enjoyable.

This kit includes parts for 3D printing on a 3D printer, but please note that non-printable parts such as screws and electronics must be purchased separately. For your convenience, we have included links to purchase these items in the build guide.

Rocky Dumper – Discover new possibilities with our models for construction sites

3D Sets Mini Truck: Rocky Dumper

Introducing new category of 3D Sets models

Why go for our small-scale construction site models?

The 1/16 scale is exactly half the size of our 3D Sets for adult cars. It’s small enough to be printed quickly and take up less space, but still large enough to have all the features and details you’d expect from a larger model. Small-scale models have these benefits:
  • Building the model is very cost-effective. You could easily build ten of them!
  • Everything is smaller, so you need fewer components with lower specifications.
  • The model is more durable, making it suitable for children to play with.
  • You can choose 6×4 for road or 6×6 for terrain drive!
We thought long and hard about what kind of tires to use on our smallest models. The easiest way how to make tires is to use Flex filament and print your own, or you can buy a LEGO one.
LEGO is sold all over the world. They are easily accessible, everyone has LEGO at home, and any piece can be purchased separately (via „Bricklink” e-stores). It’s not a problem at all to just buy the tires. If you are familiar with printing Flexible materials, you can 3d print tires by ourself. We made a special .stl which allows printing tires with 0% infill!
And if that wasn’t enough, we also used LEGO tires as the suspension dampers for the wheels! A cheap and easy solution!

Batteries type AA

Are you new to the world of model building and not sure where to start when it comes to purchasing a charger and battery? Look no further! We have the perfect solution for you.
Introducing our AA battery-powered model – no need to worry about finding the right charger or purchasing specialized batteries. All you need is a household AA battery and you’re ready to hit the road.
Not only is this model convenient and easy to use, but it’s also budget-friendly. No need to spend extra money on expensive chargers and specialty batteries – just grab some AA batteries from your local store and you’re good to go.
So if you’re a model building beginner looking for an easy and cost-effective solution, give our AA battery-powered model a try. You’ll be up and running in no time!

An easy and affordable drive solution – Motor with transmission!

An easy and affordable drive solution – Motor with transmission!
We wanted to make the build as easy as possible for children while still maintaining all the functional features you’ve come to expect from our models.
We chose the most elegant solution. A motor with integrated transmission, which is available worldwide and can be purchased at an unbeatably low price because it is used in many electronic and robotic projects.
Thanks to the choice of a motor with transmission, the axle build is easy even for children.
