Molecular Model

thingiverse

I designed and built a molecular model set for my friend who's taking O-Chem. Carbon has four available connections, oxygen has two, and hydrogen has one. I made oxygen molecules slightly larger than carbon atoms (16 vs 12 molecular weight) and hydrogen the smallest of all. I'll probably add double bond connectors later on, but meanwhile, I printed some in a different color for him to use as "Double Bond" markers. The connectors are sized 0.4mm smaller in diameter than the holes in the molecules. If there's any fit issue, just adjust the connector sizes up or down by one percent.
