Weren't you using old capacitor or resistor leads as pins though? Using something more appropriate would solve that issue.

I know, but I do not have anything more appropriate lying around (at least I don't think I do).

That may be so, but I'm thinking that with proper pins the 3d printed connector actually can work well. The construction of the pins is very important and using the wrong sort of material is going to cause the issues you're having. But if you search for something more suitable you may find an affordable and easy to purchase solution.
So I wouldn't give up on the idea so soon. Honestly using those component leads as pins for the connector is probably a terrible choice, but it was good enough for a very rough prototype. You need something else that is meant as a pin connector for anything beyond a very basic proof of concept. You could look at various connector pins, maybe some crimp type pins that you put into a housing might be adaptable to a 3D print.
One of the key goals being you want something that is very unlikely to damage the connector on the console. I feel pretty confident a solution can be found to make it work.

Yeah, you're right. I just needed to vent a bit, I realize now that it would be quite a shame to throw all of this work away. Sorry about that.
And I agree with the choice of the connector pins, old component legs were quite a terrible idea indeed.
I've looked a bit into real connector designs, and the pins for this sort of connector are usually made of brass. It's way more flexible than the component legs, which were quite stiff, in the worst case bending the pins inside the console. But for my defense, I really don't have anything better lying around at home, so this was the first thing that jumped to mind.
However, sourcing such brass pins is a whole other problem. How would someone even search for such a thing? "Brass connector pins" yielded me with expensive 2.54 mm pitch pogo pins, and "thin brass wire" (in case I would have to make them myself) got me results with 1 mm thickness or higher, which is way too thick for our purpose.
