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)

Try searching for "coreless motor", gives me lots of ebay results with tiny 7mm diameter dc motors looking like this: https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Ftse1.mm.bing.net%2Fth%3Fid%3DOIP.0qbVZk69iUxzXpp-87VHFwHaHa%26pid%3DApi&f=1&ipt=34626bb8832b480226ede8e0a44a8013a56d9217b7cb576ec699024a06297899&ipo=images

These seem pretty weak but they are cheap so i may try them if i find some from a good source. Thanks you.
