M0-M3 connections all have dupont pins shoved into the Molex cable ends

While just cobbling this together has been surprisingly stable and effective, I want to do something better. When I make a housing for the board, I should probably make some jumpers with a 4-pin JST XH for the Octopus on one end and a Molex Micro-Fit housing on the other end so the new controller enclosure is plug-and-play with the stock axes cabling.
