This is a simple suitcase like container, to store huge quantities of small items for example: SMD components in electronics, maybe buttons in sewing, or screws, nuts and bolts for wood working etc. The CAD files are open to public and are available here: [https://cad.onshape.com/documents/9e4013e130b3ea10bd0f9d1c/w/38bc45889b85fecffe18084a/e/affbfa6db401dcbec151b0fd?renderMode=0&uiState=69d4949526f137222cdfadb8](https://cad.onshape.com/documents/9e4013e130b3ea10bd0f9d1c/w/38bc45889b85fecffe18084a/e/affbfa6db401dcbec151b0fd?renderMode=0&uiState=69d4949526f137222cdfadb8)

Since the design is parametric, you are encouraged to configure the model to your liking and printer dimensions. Imo the top 4 variables in the Variable Studio named "Main" are the important ones, and are self explanatory. The "Guide" assembly tab contains an exploded view to help aid the assembly in case you are stuck, and the image below isn't enough.

Thanks
