What term an I looking for?

Sorry I don't have a picture either. If I had a picture I could probably find what I'm looking for. 

But I've seen these cubby hole setups, for lack of a better term, for holding coffee mugs. 

I'd kinda like one. But the idea of cutting so much wood to make so many little cubes is a non starter. 

Ideally this would be pass through, meaning no solid back, which makes building at home even now challenging. 

I don't have a local IKEA, but this seems like their sort if thing. 

Actually something like this without the backing piece,  and like 4 feet wide. 

Maybe there's a place I can buy precut boards that just need cut to length and installed?

Post office cubby 

In reply to Captdownshift (Forum Supporter) :

This, or Dining Room Cubbies seems to pull up the most hits

"Mug display" or "mug storage" also seem to do the trick

I was thinking post office or mail room, because they get filled from one side and emptied from the other, ie no back.

Shadowbox?

Pigeon hole storage is a possibility. 

Cube shelf will get you there. There are some cool post office and train station ones on FB. How far is Akron Ohio? This one is from a train station
