Giant Molecular Model Kit

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

  1. Slide stem into cap.
  2. Screw cap into an atom port.
  3. Repeat to assemble a full molecule.
