After working through the Tinkercad tutorials, you will have the skills necessary to begin creating your own three-dimensional designs in Tinkercad. The first object you will create and print is a custom keychain.

All you need for this project is Tinkercad and a 3D printer.


Build time:

Approximately 30 – 40 minutes

Skills needed:

  • Basic computer skills


  • Computer
  • Tinkercad – web-based 3D design software
  • 3D Printer

How to Make a 3D Printed Keychain


Step 1: Access keychain template

Log into Tinkercad, so that when you open the keychain template, it opens in your account.

Click on this link to open the template you will use for your keychain: Keychain Template-Tinkercad>

Step 3: Begin customizing your keychain

When the template appears on your workplane, you can begin customizing. To access letters or numbers, click the “A” or “1” in the top right.

NOTE: DO NOT alter the size of the keychain without first talking with an instructor! They can help you if you have a name that is too long to fit.

Step 4: Complete your design

When you have completed your design, it might look something like this. Make sure that there are no stray objects anywhere on your workplane because those will cause your print to fail.

Step 5: Group all objects together

  • After checking your workplane for stray objects, select all objects in your design by clicking and dragging over them to highlight them all in blue.
  • Once all the objects of your design are highlighted in blue, click the “Group” button at the top of the Tinkercad window.
  • When properly grouped, your design will be all one color. It is now one object and is ready to be downloaded for printing.

Step 7: Change the name of your design

Next, you will want to make sure to change the name of the design so it is recognizable as yours when it is printed.

  • Click on “Design” again in the top left menu. Then, from the dropdown choose “Properties”.
  • When the Thing Properties window pops up, select the text and delete it. Change the name of the file to be your First Initial, Last Name – keychain. (ex: FLast-keychain)
    • Then, click “Save Changes”.
