MINI 3D-Printed RC CAR by El1as.F

Before I started designing, I had set myself the following goals. It should be as small as possible, but still have all-wheel drive and have suspensions. Of course, it also has to consist largely of 3D-printed parts.

If you want to learn more about it, I also made a YouTube video: https://www.youtube.com/watch?v=RjJTNpy3MkQ

(Yes the video is in German, but I made subtitles for English and French people)

I also made a Building Video: https://www.youtube.com/watch?v=9Ftb_rpbNsk
