Okay after a little searching I have found this.. Yet it doesn't bear the quick-coupler referred to as the dremel ez-lock.
I'm assuming that the ez-lock design is patented, which is why duplicate/knockoffs are hard to find but I still have hope that someone has been in a similar situation before and found a solution.
Dickering with that little screw to change cutting wheels looks slightly inconvenient.
However, 13 cents apiece is a lot more affordable than 2 dollars per wheel.
