Remix of AndrzejG's model, that features a new "tear" 1x1 tray, the missing split color versions of 2x2, 2x3 and 3x3 trays, and a 1x1 card holder.
All tray models are direct modifications of the original 1x2 split model, so everything should fit right with the same print settings. I will be printing these for myself as well, but feel free to let me know if you find any issue with the models.
For assembly you will need the connectors from the original model page. There is where you will find the other tray sizes, the card and pen holders, and the hangers.
The author remixed this model.
