LC meter case

Improved version of the case for the the LC-100S inductance/capatitancy meter. This instrument is readily available at very low cost (approx USD 30) on ebay and elsewhere, but comes as a bare PCB without a case.

This new, improved version is based on the improvements made to my original version by linearchaos in http://www.thingiverse.com/thing:376273 . It is tuned even more, and also adds a real button for the "Func" key.

There is one variant for the 4-button and one for the 3-key version
