[machining 4 all]

Saltfever, thanks for the comments! It is good to know that my project was able to dispel the creativity of other colleagues! The dovetail is present in practically all industrial equipment, I didn't invent anything, I just used the concept. And if you don't have the tool to machine, you can make it yourself! To round the edges, just use a tool with a higher tip ratio and you minimize the problem of stress concentration!
