Hinged Heart Print-in-Place Link Bracelet

These models print in place without supports and should flex easily straight off the print bed. A little wiggling may be required to loosen the joints. 

I printed mine at 0.1 mm layer height and 50% infill. You might be able to get away with lower infill, but it probably won't make much of a time difference. Change to a contrasting color filament at 3.8 mm to see the heart-shaped hinges “pop” visually. Makes a great Valentine's day accessory. 
 

The different models have the following lengths (slightly less when the clasp is closed):

• 9 links:  182 mm/ 7.2"
• 10 links: 201 mm / 7.9"
• 11 links: 220 mm / 8.7 "
• 12 links: 239 mm /  9.4 "

I couldn't get the 12-link version to fit on the bed of my Prusa MINI+, but it will work with a bigger print bed, so the STL file is included. Enjoy, and have a wonderful Valentine's day!
