About this 3D model

This is a heavily cleaned & modified version of artur83's Penrose Triangle, which was a great design however not printable. It is now enlarged (longest dimension 99.97mm) and printable on almost any FDM printer without requiring support. Walls have been thickened at the bottom to ensure a secure footing and to minimise excess overhang angles. Best viewed with one eye closed - looking at it with 2 eyes almost ruins the illusion :)
