Aerator Remover Keys Tool

Appreciate the work of the original author, but found a few things I wanted.

1) Original was overly large; these slim down a lot and remove all the wasted infill
3) The makers mark text made printing sub-optimal
3) I preferred the "wings" found on [another design](https://www.thingiverse.com/thing:4152260) that I've remixed into this one.

Otherwise, the important sizes and dimensions are the same.

Props to the original author for including the F3D file; I've done the same.
