The face coordinates can be used as listed. For the top (i.e., the I/O), the measurements are not taken from the center. I use these coordinates:
DRILL | Size | X | Y |
---|
Out | 9.725 | -15.875 | 7.5 |
DC | 12.3 | 0 | 7.5 |
In | 9.725 | 15.875 | 7.5 |
NOTE: This is for standard 2.1mm Boss-style DC jack and enclosed 1/4" audio jacks. Powdercoat adjustments are included.
