Parametric Box with sliding lid

This is my attempt at a parametric box. I have included 4 parameters to change: length, width, depth, and corner radius. There are a few constraints for dimensions to be aware of. The corner radius must be bigger than 3mm, and the wall thickness is set to 3mm be default. The corners of the box cannot take up more than ⅔ of the box's length/width, or that will interfere with the small points that lock the lid in place. I have included 5 sets of files for different sizes if you do not want to generate your own. There is a plate in the profile for each.Poker size playing cards box (1 deck)Pencil box (for 3-5 pens or pencils)100x100x50mm box120x80x20mm boxVery small box (great for things like pills or guitar picks)If you have suggestions about how I can improve this design, I am open to feedback.
