Construct Changing Pad Topper Box

What happens here

Using scrap MDF, cut pieces to form a box-like frame that will sit on top of the changing table and house the changing pad. The dimensions for this topper are 33.5 inches by 17.5 inches, with a height of 3.5 inches. Assemble these pieces using pocket hole joinery and wood glue. Ensure the box is sturdy and square, as it will act as a secondary safety barrier for the changing pad.

Goal: Build a simple box frame from scrap MDF to create the recessed area for the changing pad, securing it with pocket holes.
