This is a compact 3D-printed fidget keychain inspired by the Ruger Mark V aesthetic.
It features simple moving parts, making it a satisfying mechanical fidget toy.
Despite its firearm-inspired appearance, this model is strictly non-functional and designed purely as a decorative accessory or stress-relief gadget.
The design prints easily, assembles quickly, and looks great in two-tone color schemes. Perfect as a keychain, desk toy, collectible, or small gift for makers.
⚠️ This model is purely decorative.
It is not a weapon and cannot be converted into one.
Assembly note
⚠️ For proper mechanism operation
make sure to insert a small rubber band (20–30 mm diameter).
