About this model

This keychain features the greek letter Psi (Ψ), the official symbol of Psychology. For a more traditional look in in Brazil, printing it in blue is recommended, as blue is the color used for the graduation sash worn by Psychology graduates. This is a remix of the original Psi Key Chain model available on MakerWorld: Modified and smoothed to improve the overall appearance. Original model credit goes to the creator of the MakerWorld version.
