I uploaded part 44139 (which surprisingly is on Studio with a slightly different geometry)  I worked at the same time on 44140 and the different spines that can be attached to them.
As Johan was asking for 44140 in the chat, I will upload my "in work" version here. I am still lingering how to best add the indents.
