Just a simple container with a lid wich I use to store my XT60 plugs. I added a small version wich is 130mm x 65mm (5,12" x  2,56") and a slightly larger version wich is 175mm x 95mm (6,89" x 3,75"). 

For the Top Part you have to use supports on the bottom. 

You can even print the large version with the Mini, but you have to adjust the raft first layer expansion for the supports on the Top Part.
