Heart of Hearts Fidget (2 sizes)

These are ‘pin art’ inspired heart-shaped fidget toys. I designed two sizes: a Small Heart of Hearts and a Large Heart of Hearts.

3D PRINTING SETTINGS Layer Height 0.2mm PLA works great 15-20% Infill No supports

Dimensions of small heart: 2.5 in. x 2.25 in. Dimensions of large heart: 3.75 in. x 3.5 in

I would recommend starting with the small heart (which takes about an hour and a half) and then try the large heart. I found the small heart printed great on my Bambu A1 with all the ‘mini’ hearts sticking nicely during print and moving freely within the print afterwards. Just in case you print it and the ‘mini’ hearts are hard to move (or stuck/fused) - I also designed a second file for each size that has more tolerance (+.1mm tolerance).

In my attached 3MF file you'll find the following files: Print Plate #1: Small Heart of Hearts Print Plate #2: Small Heart of Hearts (+.1mm tolerance) Print Plate #3: Large Heart of Hearts Print Plate #4: Large Heart of Hearts (+.1mm tolerance)

For the large heart I would recommend pre-treating the print bed with a glue stick (or hair spray) to ensure good adhesion - particularly for the ‘mini’ hearts inside the main heart. There are 51 ‘mini’ hearts and I found when I didn’t use a glue stick, some of my prints would have one or two mini hearts that would become loose before the print was done (which wasn’t catastrophic, just gave them a little rougher finish). Using a glue stick solved that problem for me:)

These are a lot of fun to play with and I think make great little Valentine’s Day gifts ❤️

Have fun printing!
