3D LED lighting display tile

I’m putting together a modular LED strip Lighting tiles built 300 mm × 300 mm 3-D printed tiles. I want each tile produced in PLA and finished with a consistent, visually appealing textured face so they read well under show lighting and can handle frequent handling during rep visits to customers...
