Racing Spring Car 100% 3D - Wind up mechanism

Thank you for your encouragement, the long transmission allows for a longer distance but the acceleration is smoother

if i printed the "all parts" then itincludes the londer transmission or the standard?

This is the standard one that comes with the parts, the long one has its own print profile

Hello, the assembly looks clean Does your spring remain compressed and the wheels not turn If so there could be several reasons - the spring is not pushed far enough onto its axle which blocks the gears on the same axle They must all have play and be free - The wheel axles do not turn correctly to check this you can roll the car on the ground forwards you should hear the clicking sound of the freewheel - The freewheel is mounted backwards when you turn the knob to wind the spring it releases the force without turning the wheels - print defect on a gear it causes a hard spot in the movement it turns a little and then locks - you can apply some lubricant and break it in by repeatedly operating the mechanism forcefully until everything is free If after checking these different points it still does not work contact me again I will help you

What material did you use

The side is not properly seated (see photo top left) it may rub on the wheel The spring is not pushed in far enough on its axle which prevents the subsequent gears from turning freely

The tires with glitter are superb! With the ABS spring, it should accelerate powerfully!

actualy the tires are TPU as your raccomandation

yesss so powerful, do also drift at start

Super!!! Thank you for the photos

If you like this model, feel free to check out the 4x4 van, it's a bit more complex to print but assembly remains simple: https://makerworld.com/en/models/1463145-vw-combi-van-spring-powered-car-mini-bus#profileId-1525903

Hello, what happened to your spring??? Is the rest of the mechanism free: the car should roll freely. Can you please send me a photo of the mechanism from underneath

Thank you for the stars and photos, it's superb !!!

Thank you very much for the feedback and the photo, to improve adhesion you can use TPU from 60A to 85A or pieces of bicycle inner tube

Nice print thanks for the photo the stars and the boost

Superb, thanks for the photo and the boost😊

Thank you very much for these beautiful photos, these stars, and this Boost Don't worry if you have washers left over, I always include a few extra For the tires, it's best to print them in a flexible material, TPU 60A is ideal, but 85A works well too For distance, you have the option to print a long gear ratio which will allow you to cover a greater distance at the expense of acceleration Feel free to check out my other spring car models; you'll find a wide selection, including highly performant ones like the GMC van (4-wheel drive, large spring, and two differentials) or very technical ones like the Hotrods (where the spring propels the car and drives a V8) Happy printing

Awesome, thanks for the photo and the stars
