Is your micro-USB charger broken? Does it randomly stop charging or simply not charge at all? Often, the only thing it needs is a tighter connection. This is what the 3D-printable micro-USB cover is designed for. It fits all type B micro-USB’s. Simply slide the cover over the metal bit and plug your charger into the device. The tighter fit ensures proper contact and your charger will be as good as new. Try this before running out to get a new charger!
