Folger Tech Heat Sink Spacer

With the latest Folger Tech 2020 extruder, when you tighten the cooling fan down, it distorts the fan. This VERY SIMPLE spacer takes up that dead space between the fan and the heat sink and prevents that distortion.
The hole is much larger than it should be to accommodate slightly different fan dimensions, such as the one I have.

It just can't get any simpler than this. It's almost embarrassing.

The newer version gives a little more clearance vertically. The first one is a tight fit.
