After you obtain your model, you might want to modify it. For our needs, we will want to at least add our name or initials to the model so we know whom each print belongs to.

• Tinkercad is the main site we'll use to edit our projects. You will need to sign-up with a free account. You can use your Google account ( including your school account ).

There are other software programs you can download on your home computer. You will not be able to install them on your Chromebooks.

• Blender
• FreeCAD
• Meshmixer
• Cura

When we're done editing our projects, we will save it to an updated .stl file for the slicer software described later.

This section is to be done after you have edited your model.

1. In TinkerCAD, click the export button to export your project to the slicer
2. Click the .stl option
3. Save the file where you can find it again
4. Open a new browser tab and go to Ultimaker by MakerBot. Make a workspace if you haven't already. You can only have 1 workspace with this account, so give it a name that resembles the work we're doing here ( eg. BMMS 3D Prints ).
5. Click the Create New Project button. Give the project a name resembling the project ( eg. Benchy Boat ).
6. click the Upload Files button
7. Click the Documents tab to see your uploading/uploaded files
8. Click the 3 dots ( burger menu ) to the right of your file
9. Select the Prepare option
10. You can now review your model in 3D space ( all sides, including top and bottom

As we get more advanced with designing our models, we will use standard image files ( JPG, PNG, webp, etc ) and convert them to 3D printable ( .stl ) files that can be added to our models. To do this, we will use the following site(s) to conver our images.

• ImageToSTL
