This is made with a mirror from Dollar tree + a 5x7 acrylic sheet (1mm thick) + one way mirror film. Internally, 40 WS2812b LEDs (from a 96 LED/m strip) are attached and driven by WLED.

Each edge has 10 LEDs and soldered with the adjacent ones (via a short 3pin wire, about 2-3cm long). But it might be ok to get 11 LEDs without solder but the corner would look a little bit crowded.

The 1mm acrylic sheet might not be ideal. Most likely a 2mm or 3mm sheet would work much better. But that's what I have for now.
