Designed these rather than paying buying chemistry kits from lab supply companies.
The connectors are designed to be printed in TPU. The flexibility can be controlled by adjusting the number of perimeters. They are slightly oversized so when squished in they are quite secure.
The scad files are included if you want to make your own adjustments
The only difference between the different atoms is the number & location of the bond locations. Carbon & Nitrogen have 4, Oxygen has 2, Fluorine, Chlorine & Hydrogen have one (Hydrogen and has a small option).
Just print in the appropriate colour for your chosen element.
A kit that's $40 list price can be printed for ~$5-6 even with the TPU being expensive.
