We finally finished making the 3D model of our project!

We spent a long time on the carriage design (the square piece in the attached vid that holds the two microfiber rollers) and getting the gap between rollers right to fit phones of all sizes, including cases. We went for a sleek futuristic look, so it had to be compact and not too big. In the end, while designing the cleaning fluid container, we realized in the end that we have only one water pump and one long pipe but 4 nozzles lol. So we have to cut them and find a way to arrange and connect them separately.

The hardest part was the middle base — it supports the carriage, phone, and threaded rods simultaneously, and getting exact measurements was annoying since several Amazon listings don’t list dimensions. We also designed two internal pillars for structural integrity that double as mounts for the UV strips.

The build splits into 6 parts: top lid, carriage, middle base, 2 parts for the shell, and bottom base for all the wiring and Arduino. This was because we wanted to 3D print this project easily without much supports.

I also added all our files and created a README to our Github repo and also created a demo video. Our project is now ready to submit for the outpost funding!

Thanks for reading! (sorry about making this a bit too long, I should’ve made this into multiple devposts)
