I looked here first but didn’t see anything quite like this so off to Gallery - Boxes.py I went. This is a combo of the electronics box, and a 3 sided box with the top shortened in Inkscape. It gives you a 5x7x7 box, with a shelf in the lid to display a 5x7 photo/piece of art.
Also the tabs are funny looking so you can pull them out without breaking the box if you want to replace the art.
(if you want to recreate with modifications I used 180x130x130 and everything else as the default on boxes.py)
It uses 2 boards, but not all of either - with some creative pushing you can get it down to 1.5.
This one uses 3mm mahogany from Ocooch for the top, and baltic birch for the interior (I only had so much mahogany ) It takes about 10 minutes total to cut out, and was hammer-tight in the fingers for me (I ended up using superglue in the corners cuz I didn’t want to break it trying to get it back apart to put glue into the fingers!)
I used to enlarge the image bed size so it would all show - but then it would sometimes have issues when being loaded the GF so I stopped…but then you have the “some of it is missing” issue.
Thank you @ptodd for answering far more timely than I did
