Dump truck (no hardware needed)

This is a dump truck made at a friend's request It features no hardware parts and axles that use 3rd generation optimized printed springs Due to comments on the water truck model, someone requested a half-door to see the interior, so this door is universally compatible with that model (Small size LWH approx: 86.7*45.6*38mm)

Notes:

1. Before printing, ensure the filament can bridge 12.4mm (Large size 18.6mm, my support-free print as shown in the preview has no sagging) otherwise the car door might not close Or be prepared to manually correct it

2. The small size parts have fragile structures and are prone to breaking Do not press the door pin crookedly, otherwise it is highly likely to break

The GIF below is the assembly diagram: Please install in order Please install in order

1.Align the hole at the end of the bucket with the hole at the rear of the car, then install the bucket pin

2.Install the door pin ensuring the direction is not reversed Note: Align the holes, install carefully, do not press crookedly, otherwise it is highly likely to break

3.Install the other parts, finally install the wheels otherwise the bucket pin will be difficult to install

4.Tilt the wheel and place it on one side of the axle buckle, then use your thumb to press the red circled area and your index finger to press the side of the wheel to apply force and push it in (using the lever principle) The other side's wheel is installed the same way (see GIF)

The green part in the image below is the support to be removed it is relatively easy to remove

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 = =!!
