  4. Email your completed laser cut keychain to drakelasercutter@gmail.com.  Put your last name in the subject line of the email.

3d prints with moving parts

Now on to your 3d printed piece with moving parts.  Remember that your piece should be no larger than 60X60X60 mm.

Complete your piece and send it to me by clicking here. 

Project Preview

 

After you have sent me your laser cut keychain design then it’s time for a preview of our next project.  SO, follow this link to an online gear generator.  While you use the tool, consider the following questions:

  • how do multiple gears interact?
  • what happens when you change the number of teeth in one gear?
  • which gear setup would you use to climb a steep hill – two big gears, two small gears, large gear and small gear combo?
