Next we check fit by suitable arrangements.
Increase size of working area, group each set of parts together, then drag around to check:
Next, modify/add geometry and arrange for cutting out of some reasonable size of stock which will fit on a machine. The largest part is 3" x 8" so we will try 4" wide boards which are a bit longer than 16" long (which will allow this to comfortably fit on any Shapeoko (my apologies to the Nomad folks).
Before we get too far, let’s mark the lid with a finger cutout:
Then we select everything and rotate it 90 degrees:
We’re going to need two boards, so let’s draw those in:
(note that you’ll need to use boards a bit longer than 16" at least for the sides/top, the bottom board can be ~12" long)
Next we arrange the parts within those two rectangles leaving room for an endmill to get into things:
and expand/modify geometry as necessary to allow cutting things out and to use a 1/8" endmill (the grooves for the top/bottom will be slightly increased in size to allow it to fit)
