Description
This is a compact 3D-printed fidget keychain inspired by the Ruger Mark V aesthetic.
It features simple moving parts, such as a sliding “bolt” and a functional trigger-like mechanism, 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.
Asembly notes
For the mechanism to function correctly, you must install a small rubber band into the dedicated groove on both internal sides of the barrel.
The rubber band provides the necessary tension for the moving parts to return to their default position and ensures smooth operation of the fidget action.
