Tools for (Dis)assembling Pratt&Read Keyboards

I had to rebush a Pratt&Read Keyboard, a rather tedious task... So instead of doing it with pliers and so (and getting mad in the process about the flying springs) i did some tools to ease the work.
The model was done with Build123d (the python files are in the package if You want to modify it) and was printed with petg, it seems strong enough.
Happy keyboardrepairing!
