Step 1: The Body

For the first step, we're going to make the body of our dragster. It does not matter the size, but make sure you have room for the rocket engine. My body is 50mm tall, 50mm wide, and 200mm long.

Step 2: The Slot for the Rocket Engine

For this step, we will be adding a slot for the rocket engine to go in, you can make the slot as long or short as you want, but you should probably make it at least 5mm longer than you engine, just in case something happens when printing. You will also want it at least 2mm wider than your rocket engine so that it can slide into the slot. On to the next step!!!

Step 3: The Front

You can make the front of the dragster look however you want. I make mine look like a rocket, but you can go for speed and do a wedge. BE CREATIVE!!!

Step 4: The Axles

We will be adding axels to our dragster on this step so that it can drive! We will be using metal washers as wheels. Look through your house to find a washer. Measure the hole of the washer. Make your axel 2 mm less wide so that the washer can fit on and turn without trouble. Make your axels double the width of your initial body, and then center it on. Make sure that your axels are not close, for the dragster will be unstable.

Step 5: The Spoiler

For this step, we will be making a spoiler to ensure a smooth ride on the dragster

Step 6: Lauching It

You launch this the same way you would launch a model rocket, except for that the dragster is horizontal, while the rocket is vertical. You will need a model rocket set for this because you need the ignition, igniters, plugs, and rocket engines. Here is a video on how to launch it: https://www.youtube.com/watch?v=-6WnAY9Qego

Step 7: Safety

DO NOT STAND BEHIND THE DRAGSTER WHEN LAUNCHING. BE AT LEAST 8 FEET AWAY. DO NOT PLAY WITH IT LIKE IT IS A TOY BECAUSE IT CAN BE DANGEROUS. TREAT IT LIKE A GUN. DON'T LOOK DOWN AT THE ROCKET ENGINE AFTER A MISFIRE. SAFETY FIRST!!! :)
