I’ve been trying to rearrange my modelling room desk (as the wife told me my models are “creeping around the room”

And I had a light bulb idea

with an old CD tower/stand.
Just blue tack the models to it and used it as adjustable mini shelves for “works in progress”
It may or may not “broomfondle” have been done already. (I’ve done a small search on cd shelf, cd, cd tower but didn’t find anything)
I'll be cutting some inserts out of plywood/
MDF or something instead of the disk covers I'm using
