Our first visor iteration had two solar panels in it and used PLA plastic. There was no PCB enclosure, and we used grooves to attach the solar panel. However, the grooves were very flimsy, the straps broke very easily because the PLA plastic filament for 3D printing wasn’t strong enough. Due to these issues, we decided to look for other 3D printing materials that would be more stable and tried designing a PCB enclosure in Fusion 360.
