Hello, Just found these 5mm shaft collars tonight if anyone else is interested... 10 pack 5mm Collars for $2.00 And also 40x40x10 cooling fans for $2.00 each... It is from a hobby company named Value Hobby While I am sure they are not top of the line, if you are on a very tight budget like me they will get you by until you can upgrade to something better. UPDATE: I found these at Global Industrial
