* Follow the directions given in the [[Handheld CNC Router#Training|Handheld CNC Router Training]] to set up the router. We will want to use the 1/4" bit for this operation.
* Mark the interior rectangle as an "interior cut." This will tell the router to cut inside of this line. Mark the middle rounded rectangle as a pocketing cut. This will tell the router to take out everything within this area (this will give us the inset). Mark the outside rectangle as a "guide." The router will not route here, but this should map onto the outline of your piece.

Perform the inside cut another 1/8" deep. The perform it again, another 1/4" deep. This should get through the entire 1/2" of the board.

When both pieces have been routed, glue up and clamp your base as you did the slices.

Unlike the wooden pieces, the acrylic slices will be one solid piece. These slices are the same 5.5" square, but they look different on the inside. Each corner is a 1/2" square piece. This leave 4.5" in between them. This 4.5" span is connected by a 1/8" wide piece. Where the 1/8" wall joins the 1/2" corner, there is a 1/16" radius fillet. By thinning this piece, we will allow more light through the acrylic walls. We will also want to add a small 1/16" diameter hole in the center of each square. This will be used to help us center our drill when we add in the insets for the magents.

There are likely many ways to do this. I have found the easiest is to make a simple part that is the 1/2" square with a 1/8"x4.5" piece attached to it. Put 4 of these into an assembly and mate them, and then save them as a part. You can then fillet it as well. Finally,
