Raspberry Pi Zero simple case for tinkering

This was designed for Raspberry Pi Zero.
I made this not only for carrying , also for Tinkering.

Components are only 2 parts.
zerobox_21_base.stl
zerobox_21_cover.stl

Please re-make, re-design or revise.
AUTODESK 123D DESIGN CAD file is "zerobox_21.123dx"

5th photo is a situation that I have tried the contents of

with adafruitr PiTFT 2.2"HAT & Retropie.

Update; 6/4/2016..."zerobox_25_cover.stl"; for Raspberry Pi Zero v1.3
[ "zerobox_25.123dx"; AutoDesk 123D file ].

A Connector for the camera-module has been added on the edge of RPi0v1.3.
Therefore, "zerobox_21_cover.stl" is no longer suitable for RPi0v1.3.
I have modificated it, made a file-"zerobox_25_cover.stl" and uploaded.
