The Hexagonal Fidget Keychain is a compact, hex‑shaped accessory designed to hold small items such as keys while providing a tactile fidget element. Its simple geometry prints well on standard FDM printers, with flat surfaces that adhere easily to the build plate and no overhangs requiring support. For best results, orient the model flat on the print bed and use a brim to prevent warping, especially when printing with larger nozzle diameters. The part can be printed in common filament types such as PLA or PETG with layer heights of 0.2 mm or finer to preserve the crisp edges of the hexagon.
