Case for electronic component tester

On EBay you can buy cheap component testers for electronic parts. These devices come as raw circuit with display and need a case to be proper operated. I designed a two piece case which houses the tester, the 9V battery and a separate on/off switch.

In my toolshed are lots of unidentified electronic components swirling around. They all land in a box labelled "to be sorted ... if time". On EBay they sell so called component testers, where you can easily put any component quickly in a zif(tm)-socket and the devices identifies the component and its key parameters. This device was a cheap buy (18€) and arrived from Hongkong without any customs hazzle after 10 days. So I needed a proper case to put this thing into.

So I came up with an openSCAD design which generates a two part case which fits together without any tools and screws.

You can either use the two stl files (rotate the cover by 180 degrees) or generate - probably modified - files using openSCAD. In the scad file are both parts include, you would have to comment out/in the one you want to generate.

I printed both from PLA with 60mm/s and 20% infill on my Ultimaker 2. You have to rotate the cover (kompo_deckel.stl) by 180 degrees.
