This is a hard cover for one of those camping gear tiny air pumps.

It has a hole for the USB-C connecter, for charging, so you don't have to take it out.

Has a bottom section for the different parts that come with the air pump, keeping things together, saving your little parts from being crushed in whatever bag you put them.

The lid is simple and snaps on top, may want to rework that in the future, I'd like it to have a hinge, but this will do for now.
