Made this using Rhino and a bit of tinkercad. Printed the face plate with adaptive layer height .08-.28 and the rest at .28. Glued the letters into the sockets with super glue. Used double sided tape on the LED strips but I made holes so it could be zip tied or twist tied easily. LED strip is a cheap remote set from Walmart. I used M3 screws for fastening it all together but it should be fine to glue.
7/1/2019 - Added an all brick version of the frame. Same letters should work and the assembly should all work about the same. The back will just glue on for this one.
