IKEA SÖDERGARN dovetail hangers system

Hi!
I present the bar system that I developed for the table at my desk.
A few words of explanation in engineering words: after a long phase of prototyping, I came to the conclusion that the best system for quick assembly / disassembly will be small modules with dovetail mounting.
I tried other, theoretically equally quick to assemble solutions as e.g. French cleat. However, they did not meet the expectations expected in them, although they were easier to print.
The big advantage of my solution is its strength and high load capacity. As you can see in the pictures I had no worries about putting a really valuable beer on the printed shelf;)
I will not hide at all that it is really an early stage of the project and I will gradually supplement the project with other models.
And here a request to you! If you have any idea what to attach, please let me know. I will gladly design it and share the results.
