Glass table for copying drawings

I don't have a glass table and my daughter often wants to trace drawings to color them, so I decided to create one By default, you can use a 215x215 mm glass (or it can be resized to other dimensions); I use one for the 3D printer bed The pieces fit together without any particular problems and the legs can be resized to make them longer or shorter You can use any smartphone flash for backlighting, or any lamp or LED you have

 

You can change the color of each plate to achieve the result shown in the photos
