Hi Thingiverse! This is my first upload here, I made this corgi statuette for my aunt's birthday and got some requests to share.
I had good results with tree supports, 20% infill and no skirt/brim/raft, but I was printing on a glass bed with hairspray. If you're printing on something like the Ender 3 Pro's magnetic build sheets, I might recommend a brim to keep tree supports in place. If you use traditional supports, you're probably safe without any build plate adhesion support, but you will add significant time to your print anywhere close to 100% scale.
Make sure to select Supports "Everywhere" and not just "Build Plate," the belly needs to be well supported.
