SummaryIf you've ever cupped your hand around a phone speaker to boost its volume, this creation is for you. It's an unconventional solution that doesn't resemble a traditional phone holder, which might be part of its charm. This device is designed to work with any smartphone, regardless of the make or model. As long as your phone is less than 82mm wide, it will fit perfectly – a safe bet for most phones measuring at least 5.5 inches across. The design consists of two separate parts: the 'cup' and the stand. The stand fits snugly into place within the cup, held firmly in position by friction. To get the best results, it's recommended to print with 100% infill, following the exact specifications shown in the accompanying photos.
