A visually striking impossible pass-through illusion featuring a rectangular form that tapers conically from one end to the other. The rectangular cross-section combined with a conical taper creates a compelling illusion where the internal pass-through appears impossible.

As the shape narrows, depth perception and perspective are distorted, making it difficult to understand how the internal path continues through the object. Designed as a display piece and conversation starter, this model prints cleanly with no supports and highlights geometric contrast particularly well in silk or gradient filaments.

 

Ideal for desks, shelves, and collectors of impossible objects and optical illusions.

 

Recommended materials: PLA, Silk PLA, or PETG


Difficulty: Easy


Supports: Not required


Great for: Desk décor, optical illusions, display pieces
