Wind-up Car + 2-cylinder engine

Hello everyone, here is a small 100% 3D printed wind-up car equipped with a functional twin-cylinder engine. The spring mechanism moves the car forward and turns the engine. The pistons move up and down, the propeller at the back rotates, and openings on the side of the engine allow you to admire the work of the crankshaft and connecting rods. You have the option to print and assemble the engine alone, it will make a wonderful fidget toy. The wind-up car is compatible with my previous models: https://makerworld.com/fr/models/1815143-wind-up-car-with-reverser-spring-car#profileId-1936884 & https://makerworld.com/fr/models/1783036-spring-car-wind-up-mechanism-4x4#profileId-1899554 You can therefore swap the wheels and transmissions to create custom models

It is a simple print and an easy assembly, however, it will be necessary to follow the instructions where you will find tips, points of attention, and advice to make your experience as enjoyable as possible. You can also watch the full assembly video at the following link: 

THE TIRES !!! In the standard print profiles, you will find rims designed to receive TPU tires with a hardness between 60A and 85A. If you do not have the ability to print this type of TPU, do not worry, you will find a print profile for rims that can receive TPU tires for AMS or even PLA. Note; with PLA tires your car will lose traction and skid

I have deliberately left significant functional clearances to compensate for tolerance variations between different printers. This does not exclude checking each part during assembly: the axles and gears must rotate freely, check the gear teeth and be careful of possible deformations when removing parts from a still-hot build plate

Feel free to test my more complex models equipped with V8 engines: https://makerworld.com/fr/models/733706-hot-rod-v8-spring-engine?from=search#profileId-665458

If you want to keep the engine as a fidget toy and give your car a new look, you have the option to print a rear spoiler with its support in a separate print profile

I hope you will have a lot of fun with this small assembly
