Introduction: Laser Cut Touchless Door Openers

About: Hi. My name is Adelle and I work for Trotec Laser, Inc. In my spare time I enjoy sharing projects for people to use on their lasers.

The application below is two in one; a hand and finger hook to open doors and drawers without touching them. Use the file provided to create your own touchless door opener to keep your hands germ-free.


  • CO2 laser cutter (We used a Trotec Speedy 360 80W with a 2" lens)
  • 1/4" (6mm) acrylic (available at link below)
  • Laser masking tape or painters tape (this is to seal off you laser bed for optimal exhaust)

Step 1: Process Acrylic

Position a 1/4" (6mm) piece of acrylic into the laser machine and cut the material using one or both of the files provided.

Laser Parameters for Cutting*

  • Power (%): 100
  • Speed (%): 0.6

*Use these parameters as a guide but make sure you adjust your settings if you have a different laser system or a different wattage.

Step 2: Cleaning Acrylic

Once processing is completed, wipe any excess dust or debris from the surface of the acrylic and remove from the laser system. Attach to a retractable, clip-on badge holder for quick and easy access.
