Im building a flashlight and i want to test if a fan in it would be a good idea but the flashlight is really small so i would need a motor thats smaller than 1 cm preferably. I found really good ones at maxon group but unless you order them in bulk(1000+ units) they cost like 400€. So do yall know anywhere i could find them? Thanks in advance! (Edit: Im a complete baffoon and forgot to specify that preferably i would need a water resistant fan. I assumed this because bldc motors without drivers are wter resistant)

    I was already planning to use a copper core pcb. This is pretty common among insanely powerfull lights. The flashlight community has some great examples. But most of these lights use resistor based voltage regulators which waste a lot of energy in the form of heat so im trying to improve on the traditional design.
