Alternative title: "Why on earth would anyone need to build a drum feeder"

I have a certain connector I use for one of my projects: https://hackaday.io/project/86954-oasis-3dp. This connector consists of a plastic body, 52 gold plated pins, and 52 springs. I get all of these parts separate, in bulk. Lets assume for sake of argument that this connector cannot be bought assembled (read, I already have 125 unassembled).

It takes 15 (miserable) minutes to assemble a connector by hand, with tweezers. Of that 15 minutes, it takes 5 minutes to place the pins, and 10 minutes to place the springs. The springs tend to lock in each other, and it takes time to take them apart. With 125 connectors to be assembled, I have at most around 32 hours to automate this process, minus whatever time it will take afterwards.

32 hours it not much for this type of development, but I am also curious to develop these tools. I think that if I can develop it now, it will take me much less time in the future (and hopefully some other people too).
