Mid-century Shelving

I have been researching shelving units and made these 3D models to analyse the construction of classic designs.

Stokkenkast means stick cabinet - and I have found few variations of these idea. I like the profile of shelves that Lutjens used in his shelves - it is both practical and pleasant to look at.

Fratelli Prosperpino's shelving is a modular solutions - shelves and cabinets can be moved around to suit the user; it would be interesting for me to see this unit in real life as I did not quite get all of the details from the photographs found online.
