I cut the Masonite close to the lines with my band saw or Dremel jig saw, then on the outside edges I used my disc sander. On the "inside" edges, I just filed them to the line, and everything got a light sanding with 220 grit sandpaper.
The holes were drilled using a1/4 "Brad Point" drill bit.

Tip on getting a very clean cut on wood or fiber board with a jigsaw: get a tile cutting blade. They are basically a diamond powder sand glued to a smooth metal. They cut wood very clean but limit the jigsaw turning radius and cutting speed a bit... They also cost a good bit, but when you have a tiling home improvement project that justifies the purchase.

Thank you... “Brad Point” drill set added to my vocabulary and my shopping cart.
Is the Dremel jig saw a hand-held device or is it configured more like a small band saw (scroll saw)?

Brad point drills are the solution. They cut without ragged edges and since they have a point, they do not "walk" or hog out the hole.

Crist, did you use some kind of jig to keep the holes in a perfect line?

No. I just center punched each one. There were a lot of holes!
