Case for Embedded Artists' Labtool:
http://www.embeddedartists.com/products/app/labtool.php

Note: there have been reports of these STL files not printing correctly. I seem to have succeeded in correcting those files now and I've downloaded new versions:

LabTool_Top_04.stl
nut_quite_01.stl

I didn't find errors in the STL file for the bottom (Labtool_Bottom_05e.stl) so I left it with that.

Mind You, I didn't print that myself because for me the old versions worked fine. If You don't succed in printing I'd much appreciate to get a feedback from You.

Oh, and no "rounded" versions this time. These I could not repair and so gave up on them :)
