Great project! I made some small tweaks: - I needed to also install the following libraries in addition to libopenjp2-7 python3 and pytho3-pip: python3-dev build-essential, libjpeg-dev and zliblg-dev otherwise neopixels would complain. - Australia has several timezones and the clock defaults to the capital city timezone. I added a --tz argument for timezone to the argparse list and modified the python code so that a pytz timezone object is passed to the datetime.now() call. Also modified the install.sh file so that the daemon service is created with my selected timezone. - Some of the colours are really low contrast and hard to see. I ran several tests with random colours and selected a colour palette with only high contrast and easy to see colours. - Agree with comments that 75/m LED strips are very difficult to find. I also printed with a 123.33% scale so that I could use the more easily available 60'm LED strips.

Could have been modelled better - the rim layer has gaps that need supports (if these were modelled to be touching this could have been printed without the rim supports) and the last heart on each side is awkwardly skewed / stretched. Model is so delicate that the first print broke while removing the supports. I edited the supports for the second attempt with normal (auto) supports and a 3x support interface layer with dedicated PLA support filament - very easily removed and came off cleanly.

I did this intiially with PETG but found it very stiff - hair sticking out like pippy long-stockings! Reprinted this in TPU 95A-HF and is fantastic. Would definitely recommend printing this in TPU.
