3D Print a Car

Use TinkerCAD and Ultimaker Cura to create a car and prepare it for printing!

Note: This guide is a work in progress.

  • Make an account at tinkercad.com.

  • Click the blue rectangle that says "Create new design."

  • On the right side, in the dropdown that says "Basic Shapes," select "Shape Generators." Toggle the "Featured"/"All" toggle to "All." Scroll down and click "More Shapes" several times until you see a green trapezoid. Drag the green trapezoid onto the blue workspace.

  • These controls help you edit the shape. The black squares and the top white square lengthen or shorten the shape along a certain dimension. The other white squares control multiple directions at once. Hold shift while you drag to keep the ratio the same! The cones move the shape up and down.

  • Click, hold, and drag the top white middle square to scale the height down to 7mm. You can also just click the square and then type 7 into the box that appears.

  • Click the middle black square on the right-hand side of the shape and type 29.50 into the box that appears.

  • Click the top middle black square and type 19.50 into the box that appears.

  • Click, hold, and drag the top upside-down cone and move it up off the workspace 13mm.

  • On the right side, under Basic Shapes, find the red cube and drag it into your workspace.

  • Click on your new cube. Use the top middle white square to set the height to 13 mm.

  • Use the middle black square on the right-hand side to set the length to 59 mm.

  • Use the top middle black square to set the width to 19.50 mm.

  • With the box still selected, find the word "Radius" on the Shape Feature menu (it says "Box" at the top) and click on the "Radius" value. Set it to 3.

  • Click to select the trapezoid, then hold and drag it so it sits on top of the rectangle. Leave some room on one side for the hood area and less room on the other side for the trunk area. (If you need to see it from above, drag around the cube in the top left corner of the screen that says "TOP/FRONT".)

  • Use the top cone on the trapezoid to move the trapezoid down by 1 mm - slightly into the car's body, ensuring the shapes are touching.

  • Find a grey striped cylinder at the top of the "Basic Shapes" menu and drag it into your workspace.

  • Use the top white square to set the cylinder's height to 100 mm. (If you need to zoom out, you can do so with the "-" key on the keyboard or by scrolling down with the mouse/trackpad.)

  • While holding the "Shift" key, drag the left white square to scale the cylinder to 5 mm. This will affect both the x and y axis. (To zoom back in, you can tap the "+" key on the keyboard or scroll up with the mouse/trackpad.)

  • Find the double arrow on top of the cylinder. (Zoom out as needed!) Click the right side of the double arrow and type 90 into the box that says "0".

  • On the box that says "TOP/FRONT" in the top left corner of the screen, click the part that says "TOP".

  • Click on the curved double arrow to the left of the cylinder and set it to 90.

  • With the cylinder still selected, hold "Control" and "D" on the keyboard at the same time. This duplicates the shape on top of the original.

  • With the cylinder still selected, tap the left arrow key on the keyboard 26 times to move one shape 26 mm away from the other.

  • Hold the "Shift" key and click the other cylinder to select them both at the same time. Then hold "Control" and "G" on the keyboard at the same time to group them together.

  • Drag the cylinders so they sit on either side of the trapezoid, touching it evenly on both sides.

  • Hover over the box that says "TOP" in the top left corner of the screen. Click the arrow that appears below it to change to "FRONT" view.

  • Use the cone to set the cylinders 1 mm off the workspace.

  • Click the top arrow on the "FRONT" box in the top left corner to change it to top view.

  • Click outside the workspace, then click, hold, and drag over all of the shapes to select them all.

  • Click the align button          and then select the middle dot on the right hand side to ensure the shapes are aligned:

  • With all of the shapes still selected, click the group button: 

  • Click the words at the top of the page, next to the TinkerCAD logo, and rename the file to whatever you like (ex. "[Your Name]'s Car").

  • Click "Export" on the right-hand side and click ".STL". The file will automatically save to your Downloads area.

  • If you are on one of our computers, it may already have Ultimaker Cura installed. Otherwise, you will need to download it from https://ultimaker.com/software/ultimaker-cura.
