Pictureframe with LED mounting

I designed this pictureframe for my sister with fusion 360. She got a acrylic picture with 3x300x400mm dimensions and she asked me to create a pictureframe. I came up with this Idea to be able to mount a 2€ LED thingy from Tedi. The LEDs fit through the hole on the back and i mounted the LEDs with a few drops of hot glue onto the little “shelfs”.
