Custom Slide lid box openscad

So I started with a design to hold my silverware in my lunchbox. then it became I could use a box for a few surgical mask in my car. I need to make it two stl file to fit my printer. Then I thought this could be useful for a lot of things. So why not make it really customizable.

So the attached STL files fit most of the Masks I have, but if you need to I've attached the openscad file. Just adjust the 5 variables to your needs.

x=195; //x inside dimension of box. Slide out comes from this dimension
y=75; //y inside dimension of box
z=6; //z dimension of inside of box
w=2;//what to print 1 =box, 2 = lid, 3 = both
r=45; //rotate to fit printer?

The box lid holds pretty tight with just friction so no need to put notches in lid base to hold in but it was a thought.
