Makeup brush cleaner tool

The next design of one of my students. She designed a makeup brush cleaner tool. With this, we have had troubles with printing as you can see on the pictures. We put inside a structure, but it didn't print it. We cannot say why. (Maybe we really forgot to put it on.) So, the tool was offset a little, but after that, it made it till the end.

The girl sayed, that she will fix it and we don't need to print it again. I will post a picture after her repair.
