Remote control caddy

I got tired of all the remotes tumbling everywhere. This is an openscad script to create a caddy for my specific collection of remotes, but the script has a set of parameters to let one create a caddy to accommodate a different set of pairs.

The droops you can see in the unsupported spans at the top of some grid holes are attributable to Slic3r letting me down on some of the bridges. Presumably your slicer will do better.
