Lockbox

Need to put a flash drive somewhere safe? Perhaps in something that makes those little things hard to lose too! Use this general purpose box to put it in. Put a padlock on it if you need too, there's holes.

It's a low security device and you can store all sorts of trinkets in it.

It provides a 5cm cubic capacity, and walls are 5mm thick.

You can print it with supports, or you can take the risk when printing the box. I let mine "cobweb" a little bit around the locking lips but it formed the lips after a couple layers, and just a little filing was all I needed to do to tidy it up a bit.

Orient the lid with the handle facing the bottom, and the hole pointing upwards, so that the lid is being built vertically upward. This will eliminate the need for any supports. It'll print nicely.

As for infill.... The more you allow, the sturdier it'll be. I used 40%
