C64 Mini joystick modification

The joystick that comes with the C64 Mini is known to be pretty bad and mine was no exception. It was very unresponsive and it was almost impossible to do diagonal movements.
This simple mod made a huge improvement for me. It is not going to make it a great joystick, but it makes it a lot more responsive and move diagonally without problems.

Just print 4 of these small caps and press them on to the parts that push against the switches inside the joystick. You need to unscrew the bottom cover and remove the circuit board to get to them, but it is not difficult.

The previous version was a bit of a tight fit.
Orientation for printing is also corrected.
