BeadSort: Machine for sorting perler beads

This is the 3D-model I designed while working on my bachelor exam.
The system that alignes the beads is derived from Scanlimes model. The model has been a great help.
The machine built from this model is working with the hardware and software I used. Following video shows a small example in action: https://youtu.be/8U88G62yCSs
The software and some kind of documentation is available here:
