Heavy-duty Armored Vehicle (No Supports, No Hardware Needed)

This is an all-wheel, no hardware needed, shock-absorbing, articulated heavy firepower armored vehicle, the springs are printed parts, the press feel is a bit stiff~ Overall assembly is relatively simple!! (The 1.5x larger version requires more force to assemble~)

Updated on 2025.8.10:

Optimized the difficulty of installing the front 2 small cannons, optimized the issue of minor first layer overflow causing roughness for the wheels and axles, and the appearance of the rear exhaust port was adjusted (see the 4 red circles in the image below)

The GIF below is an assembly diagram:

1. Assemble the red parts first, otherwise, it will not be very convenient to install

2. Tilt the wheel into one side of the axle clip, then press your thumb at the red circle, and your index finger on the side of the wheel to apply force to push it in (using the lever principle). The installation method for the wheel on the other side is the same (see the animated GIF)!!

3. Then install other parts

In the image below, the red circle (spacing about 5.8mm) is normal. If there is severe collapse, please add supports yourself~, or check if there is an issue with the filament!!

Note: 1. Both PLA and PETG can be printed. It's best to understand the characteristics of these two materials before printing to avoid printing failures!! For example, PLA can become brittle if left for a long time or at low temperatures, while PETG has good toughness. Please choose the filament that suits you!!

        2. If it's for younger children, and the parts are small and easy to disassemble, it's better to glue them firmly with 502 or other adhesives to prevent them from being swallowed!!

        3. If there are no special requirements, please do not use your own advanced process settings for printing~ to avoid printing failures!!

If your printd part has local spaghetti, or the filament doesn't stick to the build plate, please recall if you touched that area (hands secrete sweat and oil, touching it has a very high chance of causing spaghetti)  or if the build plate is dirty. The solution is to search online for how to clean a 3D print plate!! If other problems occur, please describe it in the comments section and add pictures, so it's easier for us to solve it~  Otherwise, I can't imagine the situation = =!!
