Spacer for coil (solves intermittent charging issue with some wireless chargers)

This model fits over the top of the main wireless charging coil, introducing a 2.5mm gap between the coil and the phone. This distance was necessary with the coils I bought. Without adding this gap, the charging coil rapidly connected and disconnected from the phone. With the gap, it charges reliably. The coils I bought are probably just junk, but if you also bought junk coils, this model might solve your problem!

I recommend printing with TPU, that way it also adds a nice cushion for the phone to hit when you place it in the dock.
