Water Truck (No hardware needed)

This is a car that requires no hardware, with axles using the 3rd generation optimized printed springs Some friends wanted a car with openable doors, so a water sprinkler truck was temporarily added!! The strength of the doors, latches, steering wheel, and ladder is not very high, and there are not many details inside the cab because a 0.4mm nozzle cannot print at this size If not many people like it, future cars will try to not include these features, as it takes more time to create!! Before printing, please ensure the filament can bridge 12.4mm (18.6mm for the large size, my support-free print shown in the preview has no significant sagging) Otherwise, the car doors might not close!! Or be prepared to manually correct it yourself!!  (Small size LWH approx: 96.2*45.6*40.4mm)

Do not add water to the tank; the 20 holes in the front and rear pipes will really leak....!! (The effect is not ideal, I wanted to delete it, but it's a bit of a shame to delete....!!)

The GIF animation below shows the assembly diagram:

1. Do not install the car doors in the wrong direction!!

2. Do not install the car door latches in the wrong direction, Note: Align the holes carefully during installation; do not press crookedly, otherwise it is highly likely to break!!

3. Install the 2 water pipes on the outside of the water tank, Note: Align the holes carefully during installation; do not press crookedly, otherwise it is highly likely to break!!

4. Install the water tank cover, insert it tilted as shown in the animation, and twist it down into the slot!!

5. Tilt the wheel onto one side of the axle clip, then press with your thumb on the red circled area, and press with your index finger on the side of the wheel to push it in (using leverage) The installation method for the other wheel is the same (refer to the animated GIF)!!

6. Install other parts

The green parts in the image below are supports to be removed, which are relatively easy to remove!! At the blue arrow, if the filament is of poor quality or damp, there's a high chance of sagging, which will affect the ability to close the car door Before printing, please ensure the filament can bridge 12.4mm (18.6mm for the large size, my support-free print shown in the preview has no significant sagging) Otherwise, be prepared to manually correct it yourself!!

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 = =!!
