  STEP 3

  In the printouts folder you will find print templates that will help you drill holes:

  • back template
  • side template

  Print them and then tape back template to the back of the frame and side template on the right edge of the frame. Use the appropriate drills to drill the holes. Cut the holes for the displays and the button with a knife.

  Insert the displays and diodes in the holes using hot glue.

  That's how it should look from the front
