18650 Battery Case

In the spirt of repurposing, I decided to make an insert for my 18650 batteries to fit into used Ferrero Rocher 200g (16 chocolates) boxes. There are slots for 18 x 18650 batteries. There is just enough room for the batteries to clear the lid, so I do not believe that protected, or charger-incuded 18650's will fit. I rpinted in silk PLA with an 0.6mm nozzle.
