About this model

The Dopamine molecule is all about reward-motivated behavior (also sometimes considered the pleasure-seeking molecule). This pendant was designed to hold 4mm SS16 rhinestones, but I also designed a version with just circles in case you don't want or don't have rhinestones. Though the design is pretty basic, I tried to give it something a little extra by making the connections oval/cylinders rather than just rectangles. Printing it is pretty straightforward. The only thing is I suggest 100% infill to get it as sturdy as possible since it is so dainty. Design and full assembly instructions can be found on Instructables: I am also selling the rhinestone version of this pendant on Etsy:
