Vacuum tube clip holder for IW-18/IV-18 VFD

OBSOLETE! Please use: http://www.thingiverse.com/thing:125125

Version 1 of the tube holder of a clock that I'm currently building. It does the job, but there are some parts that need refinement.

The holes on the bottom need to be drilled to correct size for screws. They are spaced 9mm apart from each other.
