Sources for FP1 parts

Sources for spares:

There is no realistic expectation that new FP1 parts will be produced again. For discussion about not being able to produce new spares, see towards the end of this topic. The official discontinuation is discussed here.

A note about batteries: A lot of suspected battery problems (especially those where the battery suddenly doesn’t charge anymore) are not actually battery problems. In these cases the issue is often a build-up of dust in the usb port (if you’re lucky) or a broken usb port (less lucky). Try cleaning the USB port first. Batteries can also be charged externally with a universal battery charger (examples) and USB ports can sometimes be resoldered by more advanced repair shops (examples).
Also see the #batteryguide for more tips. A community discussion of alternative batteries that are capable of powering the FP1 is detailed here.
