|I scratch-built this many
years ago, back in my "parents' basement" days. This monolith
measures 1" x 4" x 9" and is made of 0.1" sheet styrene.
There are balsa wood spacers inside.
The flat-black finish got a bit scuffed over time, so a fresh paint job was in order
A fresh photo would help too.
Model Source(s): Lunar Models doesn't offer a monolith by itself, but does include it in some diorama kits.
My model is scratchbuilt.
