Wheeled Mini Excavator, newly added — Breaker (no supports, no hardware required)

This is a small excavator with movable bucket, boom, and wheels, requiring no supports or hardware, and is relatively easy to assemble,the bucket and boom are installed tightly to ensure the model holds its pose!!

2025.8.15 Update: Preview images, assembly diagrams, and print profiles have been updated. The previous update information has been removed to keep the introduction concise!!

1.New component breaker small, 1.5x, 1.6x (skip printing if not needed). Installation method is the same as the bucket!!

2.Based on feedback from friends, the installation of the base and cabin snap connector is more difficult, so it has been optimized to maintain connection and prevent detachment (see the 2 red circles in the image below)!!Note: Hard filament is more difficult to install, while soft filament is easier. You can add more wall layers to the snap connector!!

3.To adapt to future models, the 1.6x large size has been changed to 1.5x large size!!

The GIF animation below is the assembly diagram: The snap connector damping of the arm is reduced. You can insert some paper into the gap before installation to increase the damping~

1.The red component's snap connector has a front and back; the longer part faces the base, the shorter part faces the cabin!!

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 = =!!
