Simple Slider Box

Needed a bunch of containers for a resource center I work at to keep track of HDMI adapters of all kinds. Couldn't find a box I liked so I quickly put together a simple concept (admittedly not the best) using 3D Studio Max. I know it is not the engineer choice of software, but it is what I was trained on.The box can hold more than one or for other things.I do not know how to create or convert to STEP/STP files so hopefully 3DS, STL, and 3MF are sufficient. I would home some awesome engineer might improve and maybe even figure out how to have it "snap" close. I don't know. Maybe someone else finds this useful?Also, blurred some labels on the finished boxes for PII reasons.
