This is a remix of my earlier small bracelet representing a chain of hearts. In this version, I scaled up the bracelet by 110% and removed the details in the inside so as to make the bracelet a bit more confortable to wear. The inner diameter measures 51.7mm and the bracelet can be scaled up to fit.
I printed it using Ninjaflex filament and the end result was better than for my previous version. However, I believe that the details would show much better with regular PLA or ABS filament.
In this version, I experimented some more with my printer settings. I used linear supports (support thickness: 40%) instead of treelike supports with the Ninjaflex filament and this made the supports significantly easier to remove post-printing. Extruder temperature: 230 degrees Celsius. Glass platform temperature: 50 degrees Celsius. Number of perimeters/shells: 3. Average print speed: 20mm/s. Skirt/brim: 8mm. Path precision: 0.05mm.
