(Print Time: 12-15 minutes approx)

If you've completed the Prerequisite steps on the Space Portal sidebar, you should be able to get here.

Select 3D Keychain

Choose the KEYCHAIN design you like, and click 'Copy and Tinker'.

Navigation and Object Selection

If you're new to 3D design, it helps to practice basic navigation and object selection.

Object Selection

KEYCHAIN_01

Note: Skip to KEYCHAIN_02 or KEYCHAIN_03 if you selected one of those designs.

Change the name to KEYCHAIN_01_[YOUR NAME]. Select the NAME object by left clicking, then ungroup it.

After ungrouping, it becomes 5 shapes (Torus, N, A, M, E).

Deselect only the torus object by holding shift+left click on it.

Delete the selected objects. If your name consists of some of the letters, you can choose not to delete them.

Click search shapes

Search for "letter". Then click "More Shapes" to view all the letters available.

Select the first letter of your name on the right, move your mouse to the left, then left click to apply

Note: Do not use disconnected letters. For example, both of the objects in the image below are 'D' with slight variation. The letter 'D' on the left is a single piece, whereas the letter 'D' on the right is a disconnected 'D'. Please use only single piece letters like the 'D' on the left.

Proceed to add the remaining letters of your name. Make sure that they overlap each other because we want to make them one piece!

Select the first letter object by left clicking it. Left click on the small white square to adjust the height. The default value is 4.00mm which is good. So let's leave it as it is and move on to the other letters.

You can create some kind of height variations for all the letters to improve readability. Please use a height value of not more than 5, and not lesser than 1.

Orbit your 3D viewport by holding right click until your name is roughly horizontal to your view.

Click TOP, then click Switch to flat view (orthographic).

Move the letters to make it a little more interesting.

Design rules:

a. You can resize your letter and rearrange them, but please make sure that your design is within the area of 60mm x 20mm (red dotted line).

b. Make sure the tallest object did not exceed 5mm.

You can check the length and width of your object by hovering your mouse over to the selected object’s small white box at the corner.

Select all the objects by using the box selection method (Holding left mouse button), then group them together.

Select Solid, disable Multicolor by clicking on it, then select white color.

Congratulations! You have completed the design!

Click the TINKERCAD icon to go back.

You can try the other designs and choose your favourite one to 3D print.

KEYCHAIN_02

Note: Skip to KEYCHAIN_03 if you selected that design.

Change the name to KEYCHAIN_02_[YOUR NAME]

Select the keychain object by left clicking it, then click the ungroup button.

Now the keychain object has been separated into 4 shapes and they are selected automatically (Cylinder with hole, Name 2x, heart shape). To view the bottom, hold the right mouse button to pan.

Top View

Bottom View

Deselect everything by left clicking anywhere in the 3D scene outside of the objects.

Select the Name object by left clicking it, then change it to your own name. Do note that this Name object is using Hole, which means that it will bevel the intersecting heart object after grouping them together. If you prefer it to emboss instead, you can change it to Solid. But please do not change the bottom Name to solid because it will affect the 3D printing quality.

For example, I have changed my Name object to my name, Yang. You can use your own name.

If you have made any mistake while following the instruction, you can use the Undo button (Shortcut key is Ctrl+Z).

There is another Name object at the bottom for you to change.

Select all the objects by using the box selection method (Holding left mouse button), then group them together.

After grouping all objects into one, the non-solid object (hole) will bevel the shape.

Congratulations! You have completed the design!

Click the TINKERCAD icon to go back.

KEYCHAIN_03

Change the name to KEYCHAIN_03_[YOUR NAME]. Select the keychain object by left clicking, then ungroup it.

After ungrouping, it becomes 3 shapes (Cat, Name 2x). Similar to the previous exercise, there are 2 Names (Top & Bottom).

Optional: Change the color to white.

Congratulations! You have completed the design!

Note

Each participant may 3D-print one keychain design. Please show your design to the 3D instructor and let him/her know the design you plan to print. Rename your chosen design by adding an 'x' at the beginning of the file name.

Example: xKEYCHAIN_01_[NAME]
