ErgoGrip Slider Fidget | Ergonomic Hand Grip Design

This mechanical slider fidget was designed to deliver a smooth, satisfying motion combined with real comfort in the hand. The grip is fully ergonomic and shaped to match the natural curve of the palm, making it comfortable to hold and easy to use for long periods without fatigue.

The internal rack and pinion mechanism creates a clean mechanical rotation as the slider moves, giving a solid tactile feel with every pull. All parts are designed with optimized clearances so the movement works smoothly straight after printing.

Every component features a completely flat bottom surface, making the model extremely easy to print with no supports required. This ensures reliable results on most FDM printers and clean first layers every time.

The design is durable, simple to assemble, and ideal as a desk toy, fidget, or mechanical stress relief tool. It prints well using PLA, PLA+, or PETG and is suitable for both beginners and experienced makers.

This is a fully functional mechanical design created from scratch, focused on comfort, smooth motion, and easy 3D printing.
