The following information is a single lesson in a larger Tinkercad project. Check out this and more projects on Tinkercad.

The term nose cone refers to the tip of a rocket, guided missile or aircraft. When designed well, the nose cone offers minimum aerodynamic resistance.
Your nose cone will fit on the end of a 3mm rod and will help guide your glider in flight.

Instructions

1. Continue to the next step.

The term nose cone refers to the tip of a rocket, guided missile or aircraft. When designed well, the nose cone offers minimum aerodynamic resistance.
Your nose cone will fit on the end of a 3mm rod and will help guide your glider in flight.

## Step 2: Paraboloid

The following information is a single lesson in a larger Tinkercad project. Check out this and more projects on Tinkercad.

Instructions

1. Place a paraboloid on the Workplane and size it to be 25mm in diameter and 26mm tall.
2. Continue to the next step

## Step 3: The Nose Cone Shell

The following information is a single lesson in a larger Tinkercad project. Check out this and more projects on Tinkercad.

The nose cone needs to be hollow.

Instructions

1. Drag another paraboloid on to the Workplane. This time make the diameter 1.6mm less in diameter and height: 23.4mm for the diameter and 24.4mm tall.
2. Make the second paraboloid a hole.
3. Select both paraboloids and click on the Align option under the Adjust option.
4. Click on the center node to align the two paraboloids.
5. Click on the other center node to align the two paraboloids.
6. While both paraboloids are still selected, click on Group.
7. Continue to the next step.

## Step 4: Making a "cutting Jig"

The following information is a single lesson in a larger Tinkercad project. Check out this and more projects on Tinkercad.

A jig can help you delete extraneous parts of your models. In this step you are going to create an exterior shape that can be used to cut your interior shape to match the nose cone shell.

Instructions

1. Drag another paraboloid on to the Workplane. This time make the diameter 1.6mm less in diameter and height: 23.4mm for the diameter and 24.4mm tall.
2. Drag a box on to the Workplane. Make it wider and longer than the diameter of the paraboloid.
3. Convert the paraboloid to a hole. Align the two shapes and then Group them.
4. Convert the grouped shape into a hole.
5. Continue to the next step.

## Step 5: Creating the Center

The following information is a single lesson in a larger Tinkercad project. Check out this and more projects on Tinkercad.

In this step you will create the part of the nose cone that fits onto your 3mm rod.

In order to create a snug fit you will make the hole .2mm larger than the diameter of the rod and cut the cylinder on two sides so that it can expand and then contract.

Instructions

1. Drag a cylinder on to the Workplane. Make the diameter 3.2mm and the height 8mm. Convert it to a hole.
2. Drag another cylinder on to the Workplane. Make the diameter 1.6mm larger than the hole: a diameter of 4.8mm and a height of 8mm.
3. Drag two more cylinders on to the Workplane. Set the diameter of the first to 8mm and the height to 8mm. Convert it to a hole. Set the diameter of the second to 9.6mm and the height to 8mm.
4. Use the align two to center the cylinders.
5. Drag a box on to the Workplane. Make the width .8mm, the length 9.6mm and the height 8mm.
6. Make the box a hole and drag another box on to the Workplane. Make the width of this box 2.4mm, the length 9.6mm and the height 8mm.
7. Align and group the boxes with the two smaller cylinders.
8. Drag two cylinders on to the Workplane. set the heights of both to 8mm.

Set the diameter of the smaller cylinder to 8.6mm. This dimension is somewhere between the the two cylinders with diameters 8mm and 9.6mm.

9. Align and group these two cylinders.
10. Convert the last shape to a hole and align and group with the small cylinders intersected by boxes.
11. Group the larger cylinders and align the new shape with the last shape created.
12. You should have a shape like the one below.
13. You will need this shape for your connectors. Rather than recreating it later, move a copy to the side to use later.
14. Continue to the next step.

## Step 6: Nose Cone Interior

The following information is a single lesson in a larger Tinkercad project. Check out this and more projects on Tinkercad.

The next step is to connect the center to the shell.

Instructions

1. Drag a box on to the Workplane and set the width to .8mm, the length to 24mm and the height to 8mm. 24mm is selected because it falls somewhere between 23.4mm and 25mm (the wall of the paraboloid).
2. While the wall is selected, press CTRL/Cmd+D to duplicate it. Rotate the duplicated box 60 degrees.
3. Press CTRL/Cmd+D to duplicate and rotate again.
4. Drag a cylinder on to the Workplane and set the diameter to 9.6mm and the height to 8mm. Make it a hole.
5. Align the boxes with the cylinder, then group them.
6. Align the walls with the center and then group them.
7. Align the interior of the nose cone with the jig and then group.
8. Align the interior and exterior of the cone tother and group them.

9. Continue to the next step.
