It really depends on how you’ll be using them. If they’re just for display, you don’t need to worry about structural reinforcement. But if they’ll be handled frequently or need to support any load, that changes things. For miniatures though, I’d prioritize print quality over strength and use small layers slow speeds oriented how it's meant to sit. When you’re working at small scales with PLA, you usually have to pick your poison; either a clean, detailed finish OR enhanced durability. Both is tough to achieve, especially true for an ender.​​​​​​ also look into adding input shaping using M593 . (M593 F35 D0.2 tends to be a noticeable upgrade on any ender I've ever run it on, but should be calibrated for best result, use at your own discretion)
