This simple key ring works better than you might expect for a little piece of plastic! Easy to print in place with no supports required, just separate the small gap after printing. This is a heart shaped variation, roughly 1" top to tip. I wouldn't dangle my Lambo keys from it, but it is fairly sturdy.
Printing Guidelines
- Print with 4 shells/perimeters to create a solid part
- 0.16mm layer height separates easily after printing
After printing, the gaps should separate fairly easily. You may need to use your clippers to split the ends first, then the remainder of the ring should pull apart.
