My eldest daughter lost a friend and teammate in the Austin, TX area floods of July 4th, 2025. We were looking for a commemorative item to make for the team in her favorite color, yellow. We ran into Flexi Heart by MrViddy, tried out various sizes and settled on 70%. We were about to start printing a large batch to distribute to the team when my daughter had the great idea of making it into a keychain, so they can hang it on their team bags!

The model is scaled to 70% of original, at this size the hole is ~3.6mm. We print primarily in PETG, different materials may heat shrink the hole somewhat, but it worked well for us with a regular ball bead chain. Print in image is PETG, 0.6mm nozzle, 0.3mm LH, 3 perimeters, 3 top layers, 3 bottom layers.

This is for Brooke, you will always be in our hearts ♥
