Oversized kit for demonstrating molecular structures.
Options
Atoms
1-Bond
2-Bond
2-Bond Alternate (120 degree offset ports)
3-Bond
4-Bond
Hydrogen – A smaller version of the 1-bond atom.
Bonds
Bonds come in multiple sizes and two style. Default stems allow atoms to rotate freely. Locked stems prevent atoms from rotating.
Long Stem
Medium Stem
Short Stem
Mini Stem
Flex Stem Long
Flex Stem Short
Caps
Caps are used to secure bonds to an atom. Bonds are free to spin after assembly.
Default – Simplest option
Split – Tighter grip on bonds, but comes in 2 parts. This is the recommended cap when using flex stems.
Alt – Use with you own custom bond materials: bungee, rope, etc.
Printing
All parts can be printed in PLA or PETG, but avoid brittle PLA blends.
Flex stems are best if printed in PETG or a rigid TPU (95A/98A). If printed in PLA, the flex stems will eventually deform.
All parts can be printed without supports. However, some sections of the interior threads have significant overhangs that require well-tuned cooling.
Test print a 4-bond atom, a default cap, and a short stem to check for proper fitting. If the fitting is too loose, you can get tighter results by adding a very slight fuzzy skin to the relevant surfaces.
Assembly
Slide stem into cap.
Screw cap into an atom port.
Repeat to assemble a full molecule.
