A hardened ICBM / FOBS missile silo.
The perfect gift your friendly WoB-addicted neighbour. ^^
The model in the default picture was printed in "White, Strong & Flexible, polished" and painted by a moderate skilled painter (me).
Due to the small size and Shapeways handling fee, this model is much cheaper as set of six
(ppu $1.50) missile silos.
