I read your design and it is completely open source, It is very commendable.
I noticed that you use two 617DB-1023 = P3. I don't understand the purpose of this design. Maybe it is to compensate for physical asymmetry?
In that case, can it be replaced by TCM1-63AX+, it is a physically symmetric structure, and its cost is much higher, but I also noticed that TC1-1-13MX+ seems to be physically symmetrical too.
