Fidget Heart Keychain

This Concentric Heart Slide Fidget Keychain features multiple nested heart walls that slide smoothly up and down against each other, similar to popular concentric star fidgets. The motion creates a satisfying tactile feel. Designed as a print-in-place model, all heart layers are already assembled and free-moving right off the print bed. The integrated keychain loop makes it easy to carry everywhere. Great for stress relief, focus, or as a thoughtful gift.    • Layer Height: 0.2 mm  • Nozzle: 0.4 mm  • Infill: 10–15%  • Supports: None  • Brim: Not needed
