3D model description

The missing square puzzle is a visual illusion frequently employed in mathematics instruction to guide students in reasoning about geometric shapes. Its primary objective is to discourage reliance on visual depictions and encourage the use of textual descriptions and geometric axioms. In this optical puzzle, two configurations, apparently forming 13Γ—5 right-angled triangles, are presented. However, one of these configurations introduces a 1Γ—1 void within it. The intrigue arises when individuals attempt to compute the respective areas of both shapes and recognize a seeming incongruity - the shape with the void appears as if it should have a smaller area. In reality, both shapes possess the same overall area, creating a paradox that underscores the significance of precise definitions and logical reasoning in geometry.

3D printing settings

*This was printed and tested on an Stock Ender 3 using Cura as a Slicer with the next parameters: *

-Density infill: 10%

-Layer height: 1.6mm

-Print speed: 60mm/s

-support: none

-Bed adhesion: Raft of 3mm for the base object so it does not warp up

*I hope you guys enjoy it :) *
