Spinning Heart Keyring

thingiverse

A fun heart keyring with an inner heart that can spin. The spinning joint is created with filament pieces. Easy to print! Try out different color combinations! Post-Printing Assembly (see pictures): Step 1: Print parts and cut filament. Print the Outer and Inner hearts, and cut two pieces of 1.75mm filament one 12mm long and the other 10mm long. Step 2: Insert the filament. Insert the 12mm long piece in the bottom of the inner heart. Add the 10mm piece to the top of the inner heart (be sure to push this all the way in). Step 3: Main assembly. Insert the bottom part of the inner heart into the outer heart first. Then snap in the top. After the top is in place, push up on the inner heart so that the filament is in a far as it will go into the outer heart. Step 4: Add glue. Rotate the inner heart 90 degrees and add a little super glue to the joint where the filament is inserted into the outer heart. How I Designed This I designed this as a gift for my daughter (6 years old). She wanted to add it to a zipper on her backpack.
