This is a remix of the original stackable Hotwheels display case, but made taller or 4wd vehicles, and a wider and deeper groove to allow for bigger wheels. V2 also has a clip at the back to attach to a backing board with a small screw when stacked higher.

Still compatible with the original shorter version. I've been printing with 15% infill which seems to work fine.

Add your own text, or none at all, I found raised text works better than indented.
