This 2D puzzle that combines intersecting plungers and circles comes after working with the idea given by Bram in the forum to make a more thematic variant than Butterfly 2D.
He has also somehow directed the evolution of the model for which the inventor thanks him.
As for the name, the inventor pays homage to David Litwin, whose Elemental (Neon) has a similar mechanism.
Helium, like Neon, is also a noble gas, but lighter, just as this model seems to be in relation to David’s design.
The differences lie in the fact that the plungers used here are curvilinear and there are also intersecting circles.
Consideration has been given to fixing the plungers and stops with screws so that they can be removed and played with without the restrictions they impose.
By having one type of stickers for front and back, the puzzle has 2 levels of difficulty.
Printed in PETG plastic
Thickness: 9.6 mm
Diameter of inner circles: 38 mm
Weight: 132 grams
