Display stand for core memory module

Display case for a 16x16x6cm core memory module (of unknown origin) covered by a pice of glass roughly 20x20x3cm
The particular piece of glass I used turned out to be 20.2cm wide in the top, så I have designed the main piece for that. Sketchup source is included if you need to adjust
Coreframe-1 is the main display piece. -1b.STL is the foot, where as the 1b Sketchup file contains both pieces
