Figurines, especially smaller ones, are best printed using specialty resin printers or 0.2mm nozzles. Currently, I only have 0.4mm nozzles, however the 0.4mm nozzle still provides high quality finishes.
For a wide, varied and completely free selection of DnD Figurines, see MZ4250's Printables's site: https://www.printables.com/@MZ4250
There are a LOT there. The pre-supported models are for resin printers, so feel free to send me the non-pre-supported. Pre-supported can work though, but results may vary.
