Summary

Allene with orbitals separated so they can be printed in different colors

Instructions

This is allene with separated orbitals, so they can be printed in different colors. I’ve provided two versions of the sigma skeleton: One has all three carbons connected, the other has one carbon separated so that it can be turned 90 ° for printing. Print the sigma skeleton in gray. Print both X orbitals in another color (blue) and the Y orbitals in a different color (green). Then put the whole thing together. Both X orbitals should fit on the printing platform, so they can be printed at the same time. The same is true for the Y orbitals. The pins for the X and Y sets of orbitals are different, so they should not get mixed up, but you may need to flip them over to get the pins to fit into the carbons correctly.
