The m-pad-2.1 Eagle library has the 2N7000 TO-95 transistor layout wrong. I had to fix that. One pushbutton switch was inserted backwards. I added silk screen markings to make the orientation clear. I ordered an updated set of PC boards from OSH Park. Meanwhile, I created a drill template in Adobe Illustrator. Here is a jpg of the file.
The following drawing shows the hole sizes. Note, this is not to scale.
