Calling this guy done. Need to actually take good pics but sharing for now to get hopefully get some eyes on this community.
75mm scale Loot Studios Froggy Warrior. Printed on an Elegoo Mars 3. Painted with Kimera Kolors acrylics

i personally have not gone below 32mm - although I am doing an Intelligent Qube diorama and the little dude is perhaps of that scale - he's a man in a suit and fully printed about 4.5cm tall - maybe that is close to that scale. I will say that I tend to print things i want quality at 35um layer height (default being 50um). The mars 3 can go to 25um layers but i honestly don't see much of a difference. At those layer heights I believe 15mm can capture details but you may have to dial in your printer first - honestly that's not a big deal (spend a day with a bunch of cones of calibration prints and you'll be dialed in in a few hours). with more modern printers adding "K"s to their specs - those may be able to handle that scale a little better due to fidelity/pixel density but i doubt you'll find one at the price point of a mars 3.
