You

A small spring-powered car from PLA. It can be fully printed, and a small number of parts can be purchased according to options. You can also choose to disassemble it and change the gear ratio or color.

The geometry of the spring has been optimized for a nozzle of 0.4mm. The main components and wheels have standard parameters with a length of 4 weeks.

The edge of the wheel axle is 5mm

You need the "main components", "wheels", and "axles" from 3MF, and then you'll have everything you need.

Everything can be printed using PLA, except for the tires, which I recommend printing with TPU. Note that the wheels of TPU tires are different from those of O-ring tires. If you want to drift, don't put on the tires ;)

Have a great time printing!!!

The co-pilot

Here is the cleaned-up version of the information:

Introduction to the spring-loaded car kit:

Materials and assembly:

• Printable parts: main parts, wheels, and axles.
• Materials: All components except for the tires are made of PLA
• Tire note: The wheel design of TPU tires and O-ring tires is different. When drifting, avoid using tires.

Geometric shape of the spring:

• Optimization: Designed specifically for 0.4mm nozzles.
• Floor height: 0.2mm.
• Main components and wheels: standard parameters, with a circumference of 4 units.
• Wheel axle: edge 5mm.

Customizability:

• Gear ratio: The gear ratio can be disassembled and modified as needed.
• Color options: Customizable colors.
