Designed to be printed vertically. I print with a 0.6 nozzle on a G10 build plate so you may need to adjust my suggestions as they are not typical. For the keychain version I go with 1 wall and 20-30% infill which should give it a bit of squish and a soft feel. For the dog collar, two wall and 20-30% infill, more won't really help because everything is so thin. I printed the overhang with that the collar slides through manual tree supports only on the very bottom edge. To install, remove Tile from any ring then Tile should slide into sleeve with minimal effort and you can reinstall. I recommend using fuzzy skin with a very small thickness (I used 0.15 and it looks much better in person than the photograph shows) but that's a personal choice.
