Housing for "big 7 segment timer" project

Housing for a small project, using two scavenged LSD23265-10 70mm displays, an arduino Nano, a speaker, two STP08CP05 shift registers and a few switches. Originally I planned using the Arduino only for development, then later shift the project to an Attiny25 or similar.

Sorry for the bad photos. None of my cameras could capture it right.

The housing curled up on the edges, I recommend heating the printbed or applying adhesive.
