About: I'm Mario Caicedo Langer (M.C. for short), a Colombian STEAM educator living in Azerbaijan, BSc in Naval Sciences and former Navy officer. I am a CAD and 3D Printing enthusiast and an artist specialized in jun… Searching on Instructables, I found this tutorial from DotatDabbled. Very interesting, cool and well executed. But considering my objective, I have the following issues:

Now, draw a parallel line on each side, distanced 1.65 cm from the center line (3.1 cm + 0.2 cm = 3.3 cm between rails; 3.3 cm / 2 = 1.65 cm).Conversely, you don’t want to buy a set that will be too difficult if you are buying it for a younger sibling or relative. For those just getting into Hot Wheels, it is wise to buy them something that will spark their imagination, but not be over complicated enough to kill their enthusiasm.

I made two prototypes and tested them with three different toy cars: a Hot Wheels "Batman Live! Batmobile", a Matchbox "MTN XT" and a generic bootleg car (suspiciously branded "Motor Wheels"). I'm in the process of improving the design, but until now, I'm happy with the results. Keep collections to yourself or inspire other shoppers! Keep in mind that anyone can view public collections - they may also appear in recommendations and other places.

corrugated cardboard or wood rectangular piece (I used 16 cm x 7.5 cm, but maybe you will have better results with one of 18 cm x 7.5 cm) My idea was to make a Hot Wheels launcher using simple materials, as a project for teaching kids in a funny way about mechanical engineering, specifically about the potential and kinetic energy concepts.
