Need USB Dustcaps and FIrewire Dustcaps

Sometimes when you buy a device with USB ports, they have little caps on them (apparently I learned these are called dust caps), covering the USB hole, I have yet to see these for Firewire though.

I have exhaulted all my search efforts to find these for sale anywhere, like say a bag of 10 or 20 Dust caps. I would like to cover some front USB ports when not in use because of Dust and Dog hair accumulation. No I do not want to use tape.

It seems like these are sometimes bundled with new bought devices, if anyone knows where I can buy some, I would more than appreciate to be pointed into that direction.

Thanks in advance :slight_smile:
