Hollow things are usually things with curves, not usually things with large flat areas.
Also without active cooling you'll get more sag and less bridge.

For the sake of adding a couple grams infill, and a little extra printing time - but getting a perfect model every time. I usually add the infill.
I know I don't need to heat the bed with pla - but making it warm keeps all the variables as samey as possible for consistent results.
That bracelet is totally cool! Wow I will have to try one of those!

Thanks to you both on the infill feedback. I figured that was probably it. I tried it again on 20 infill and a little smaller so I could test it quicker and it worked good. Will try it bigger again and make sure.
