Ive always wanted one of these molecular models,
and now its just a matter of printing one out!
The biggest object is the base which needs at least a 14 x 14 cm build-platform.
The STL-files are optimized for the Replicator platform,
but can easily be rearranged to fit your printer.
I used a 600 x 5 mm metal rod to slide the pieces over, it helps to keep it all together.
