## **Step 1** - Preparing acrylic plates

> **Each acrylics plate is recovered with a protective layer on both sides. Peel the protective layers slowly and insure no left-over sticks to the plate.**

> **Because of the die-cut intricacy of the front panel, the laser cut process might have left the scrap pieces in place. You will have to use a a tool (e.g a pen or a flat screwdriver) to push out the scrap pieces.**
