Spinning Heart Keyring

thingiverse

A fun heart keyring with an inner heart that can spin freely. The spinning joint is crafted with precision using filament pieces. Easy to print, and the perfect canvas for experimenting with different color combinations! Post-Printing: Assembly (see pictures): Step 1: Print parts and cut filament carefully. First, print the Outer and Inner hearts, then cut two pieces of 1.75mm filament - one 12mm long and the other 10mm long. Step 2: Insert the filament pieces with ease. Place the 12mm long piece at the bottom of the inner heart, followed by the 10mm piece on top (make sure it's fully inserted). Step 3: Main assembly comes next. Insert the bottom part of the inner heart into the outer heart first, then snap in the top. Once the top is securely in place, push up on the inner heart to ensure the filament reaches its maximum depth within the outer heart. Step 4: Add a reinforcing touch. Rotate the inner heart 90 degrees and apply a small amount of super glue to the joint where the filament meets the outer heart. How I Designed This: I created this heart keyring as a special gift for my 6-year-old daughter, who wanted to add it to her backpack's zipper.
