I originally had the idea to have a man sat with his dog in front of a camp fire. I made the man and his dog, and had started creating the camp fire when I came across this model https://www.thingiverse.com/thing:2987763 by Igotit. It was exactly what i had been trying to build, but was modelled to hold an LED tea light. I've included his model in the build photo.

Print in PLA - the supports come off much easier than with PETG. 

I used automatically generated slim tree supports on the build plate only. 15% infill, and whatever temperatures your filament recommends, or that you have found work best.
