Clean all laser cut and engraved pieces using a damp cloth. Glue the two MDF parts together and add the acrylic piece on top. It is important to make sure that all pieces are positioned precisely on top of each other. Use an angle stop if necessary to avoid the parts moving. Next, remove the backing material of the TroLase lights and stick them onto the acrylic. Finally, insert the stands into the slots at the back of the display.
