Identify the "middle" acrylic piece. This is the only piece not spoken for yet. It has a small round
bite out of one end, and a large square bite out of the other (these are the top and bottom,
respectively).
The case is assembled using "T-slot" construction. Holding the middle piece, insert a nut into the
cross part of a "T". Place one of the side pieces, using the alignment slot toward the front, over
the corresponding tab on the middle piece, then insert a screw into the hole that's aligned with
the nut. If this is a dexterity challenge, the nut can also be held with tape:
Make sure the tops of the two pieces are correctly oriented. Insert a second nut and screw, and
just finger-tighten for now.
