Note! Following directions, step-by-step, is REALLY important on the these assignments, especially when exporting, naming files, and where to put the files.

Assignment #1: Google Sketchup Basic and Block #1

Goal: To use a 3D software to create an object to be printed with the 3D printer. (online version doesn’t have 3D text)

Basic directions Get your earbuds, login and watch the following video: How to draft block #1

  • Insert the picture of your Block #1 to a new Google Docs.  Name the file your last name and block 1.  For example: Smith block 1
  • Turn this doc in via your Google Classroom assignment.

Assignment #2: Google Sketchup -Keychain

Goal: To use a 3D software to create an object to be printed with the 3D printer. (online version doesn’t have 3D text)

Basic directions Get headphones, earbuds, and work on Key Chain 3D printing project by watching Part A Part B and finally Part C using Google Sketchup. Make sure you’re pausing your video and doing what needs to be done. Do NOT try to watch the entire movie first. Note: a mouse will be brought to you by one of your classmates. Carry your laptop with two hands!

Rubric: Total project points based upon:

  • 20%: Completed project on time
  • 30%: Individual Effort towards completion of goal
  • 30%: Preciseness / Following directions
  • 20%: File name correct and turned into the correct folder

Assignment #3: Draft and object from a Picture

Click on the picture below.  Start a new Google Sketchup file and name it your last name and the words ‘Axle structure.’

Use the dimensions in the picture to draft the object.  THEN – copy and paste your object and with the copy alter the object.

Assignment #4:  Designing something for your solar car

Goal: Using the skills you acquired with sketching/Google Sketchup, follow the design process to create a piece for your solar car

Steps: Students should first create a sketch in their composition books with rough dimensions and check with the teacher before starting in Sketchup.


  • Object should be totally designed by student – not downloaded
  • Students can work in groups of no more than 4, but each student should have their own sketches in their own composition book
  • Object should not be any larger than 100 mm x 100 mm x 100 mm
  • Minimum ‘thickness’ should be no less than 3mm.


  • Axle holder
  • Guidance system
  • The actual chassis itself
  • Motor holder
  • adjustable solar panel holder

Saving your work in Google Sketchup

  1. File / Save or File Save-as
  2. In the Save in box, click the down arrow and choose your S:drive. Do NOT EVER leave it in ‘My Documents.’ (Note: if you somehow get disconnected from the wireless, the files you’re working on get put into a ‘location’ that gets deleted when you log off)
  3. Type in the correct file name using class file-naming conventions. For instance, 7C5 Bill T Battery holder where
    • 7 stands for your grade level,
    • the C stands for the term,
    • the 5 stands for the period,
    • you put in your first name and last initial,
    • and finally a one or two word description of the activity.
  4. Click the Save button

Export STL file

You must ‘export’ the correct type of file so it can be printed using our 3D printer. Right now, your file is an .skp and you need it to be an .stl

  1. If you haven’t already done so, save the file into your S:drive. If it’s already been saved there, make sure you do a File/Save
  2. Next, File / Export STL Make sure it’s the Export STL and not just Export
  3. Change Export Unit to Millimeter
  4. Direct the file to go be exported: bupublic/@thonnings/!!classroom @collaboration/3D Turnin folder
  5. Once the file has been exported, go to that folder in bupublic and make sure the file ‘REALLY’ was exported
  6. Objects will be printed in order that are on that list. You may or may not have your choice of color.
