EDF prototype adapters for Rimfire 35-30

This is a remix of JeanT's EDF prototype that includes a fan with a modified shaft size of 6.5mm, and a modified engine mount that has all four holes in a 9.5mm radius, increased countersinking with added tapered screw head recessing, and an increased collar hole size.

The engine mount is also now scaled to the correct size, unlike the source of this remix (I cannot believe the author is aware of that problem with the original design but has never fixed it).

This fits my Rimfire 35-30-1250 engine. Yes, I'm probably dumb for trying an EDF at such low RPMs, but its the only engine I have, and I want to play around with an EDF if at all possible. I have not yet tested this, as I'm waiting on a 3S lipo, so don't blame me if the load burns up your gear.
