Road Sweeper (Multi-part Articulated, No Hardware Needed)

This is a road sweeper with no hardware needed and axles using a 3rd generation optimized printed spring!! Some friends previously wanted a hollow front windshield, so I made this as a test. Hope you like it. The wheels are rotatable, and the cleaning sweep support arms are articulated (with slight damping)!! (Small size LWH approx: 86.5*45.6*41.2mm)

Notes:

1. Because the entire small car is quite small, the doors, clasps, steering wheel, and stretcher legs are not very strong, and there are not many details inside the cockpit. I personally squeezed the A-pillar hard, and it didn't break..!!

2. Before printing, please ensure that the filament can print a 13.1mm overhang (large size 19.65mm, mine has no supports and no sagging), otherwise the car doors might not close!! Or be prepared to manually correct it yourself..!!

3. The tailgate is quite loose and has no damping, it doesn't mean the clasp can't hold..

4. Installing the several cleaning parts requires quite a bit of force!!

The GIF below is the wheel assembly diagram:

Tilt the wheel onto one side of the axle clasp, then press the thumb to the red circled area, and apply force to the index finger to the side of the wheel to push it in (using the lever principle). The installation method for the other wheel is the same!!

The GIF below is the car body assembly diagram:

1. Since it's quite simple, there will be no text description!! Please pay attention to the cockpit pin installation. When using a hard object to push it in, make sure not to press it crookedly, which could cause the pin to break!!

2. The tailgate clasp needs to be bent a little to install it properly!!

The image below shows the support (green part) that needs to be removed. The parts at the blue arrow require removing the skirt!!

The next project is expected to be a cold weapon similar to a small tachi!! The tanker truck project is on hold for now, haven't figured it out yet~ ~

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 = =!!
