Makeup brush cleaner

My wife uses makeup but she has a hard time cleaning her brushes when she is done. We saw some other designs on thingiverse but they all seemed hard to hold. I designed this one because it is easy to hold, 4" long by 2.5" wide, and the sides help hold some of the cleaning solution in it.

I have included the Fusion 360 file if anyone wants to edit this.
