I added the feet and am happy that the box can now stand the right direction for display:
I used a single washer between the foot and the metal to make sure the distance was even.
I ended up using left over quarter round to use for mounting the led strip light inside the box. The led strips are in the mail so I'll wait to mount everything.
I also bought a small piece of 1/4" thick mdf to use as a cover. I need to trim this to fit and paint it black. This will cover the plexiglass and lights inside the box and act as a base for the box foam:
I'm planning on pluck foam so I can semi-customize the storage.
