Military Coin Holder Insert for Melissa & Doug Wooden Box

I needed a storage/display solution for my coins, and I had this nice wooden box from my son's toy collection, so I designed an insert to go inside and tilt the coins slightly for display. 

I've included the step file for easy editing in case someone wants to use the design for a different dimension-ed box.
