Magnetic Atomic Radius Periodic Table Puzzle

Bring the periodic table to life with this modular magnetic model!

The block of elements snap together using magnets, forming a tactile and interactive periodic table that you can rearrange and expand. The height of each element block represents its van der Waals atomic radius, scaled precisely at 1 millimeter = 4 picometers, giving a true 3D visualization of atomic size trends across the table.
 

Perfect for STEM classrooms, science displays, or chemistry enthusiasts, this project makes abstract data visible and tangible. Print it in multiple colors to highlight different element groups or use uniform tones for a sleek scientific display.

Whether you're a teacher, student, or maker, this is a great conversation starter and an eye-catching educational tool!
 

Features:

     -Accurate atomic radius scaling (van der Waals)

     -Magnetic snap-fit connections for modular assembly

      -Printable in standard PLA with minimal supports

      -Great for teaching atomic trends (groups & periods)

      -Elements without real atomic radius are set to a fixed height (mostly towards the bottom)
