I had a look around, nothing in Gimp that I could find. There an ImageMagick 'box' maker although from memory it is a bit complicated.

Someone might come up with something. One question. Are you starting with a 'flat' image.

Nothing like automated, a very hands on method   In the screen shots:

Starting with a 'flat' image
Unified Transform will rotate / scale / skew all in one operation.

Used the skewed layer to make a stack of 'edges' in a layer group then the align tool to 'extrude' using a small  offset.
(while writing that, I remember there are extrusion scripts around, I will see what works with Gimp 2.10)
The example you gave has the edges fading to transparency so apply a layer mask and gradient to the layer group.


Not going to use the drop shadow tool, duplicate an edge layer, make it black, gaussian blur, move, adjust opacity. Easy.
