I somehow broke the leg of the power switch of my gameboy color and i wasn't able to find some replacement switches specifically made for the gbc, so i went into tinkercad and made this.

This thing replaces the plastic rail inside the switch itself which holds the metal pins.
It might not be very optimized and getting this little pin back into the printed rail was a little bit complicated, but this could be the case due to me trying to do it in place with all-purpose glue...but in the end it certainly does the job and my gbc is working fine again.
