I've pretty much got the box part finished... but I haven't added the load compartment yet and was looking to see if anyone had any advice for the design. I had been considering attaching a felt pouch, but am open to other ideas.

Hey Geoff, am working on something similar now. Load chamber will be disguised as a small wrapped gift and be magnetically attached. Can remove and display the gift at the end and box is clean.

My box is cube shaped as opposed to the more traditional design which is narrower on the sides with a load compartment that nearly fills the interior. I opted for a wooden compartment that was wedge-shaped to hold the load items at an angle for easier access.

That's a clever idea.
