Students will follow a CAD tutorial video in Fusion 360 or Tinkercad to design their own version of Armie.


The Pandemic Products lesson plan will equip students with the foundational knowledge and skills they need to successfully produce unique 3D Printed solutions to reduce the spread of infectious viruses. Using a process of research, simulation, design, testing and final product iteration this project will teach students:

  • About virus transmission on surfaces via an animation explainer video
  • How to assemble and analyze their own hands-free Armie device
  • How to use Tinkercad or Fusion 360 to improve the design of Armie to suit door-handles in their home or school.
  • How to storyboard their daily routines to identify objects that have the potential to spread viruses, before prioritizing and selecting which handle to design a unique solution for
  • How to use research, simulation, and measurements to generate a list of design criteria and constraints
  • To create multiple sketch options and gather feedback on their designs from peers or potential users
  • To use 3D design and 3D printing in an iterative process to make functional solutions that limit the spread of viruses

The course will instruct students on how to storyboard their daily routines - highlighting objects they touch that have the potential to spread viruses.


This lesson plan was inspired by Armie, a hands-free device that was created to promote the use of arms of open doors or drawers.

While many manufacturers have turned their focus towards the production of personal protective equipment, PrintCity set out to create a hands-free handle design that can be attached to any existing handle whether it is on a drawer or door. Although the design fits onto a wide variety of handles already, there are many situations in which further modifications are needed – this provides the perfect opportunity for students to get creative with designing their own solution while simultaneously reducing the risk if viruses entering the body through the touching of eyes, nose and mouth.

Armie can be modified to fit a wide range of different cabinet or door handles.


  • Example hands-free design solution - Armie (STL and PDF assembly instructions)
  • Project introduction and explainer video (MP4)
  • Product analysis and storyboard worksheets (PDF)
  • TinkerCad and Fusion 360 tutorial videos guiding students through the process of designing Armie (MP4)
  • Assessment Rubric (PDF and Google Docs)


This lesson plan can be incorporated into mathematics, design technology, citizenship, and computing course work. The material can be adapted for students ages 8-16 and the curriculum is aligned to ISTE, NGSS, CCSS, and UK National Curriculum standards. A comprehensive list of standards met is included with the lesson platform.
