My Zortrax M200 Plus has been repaired, and after a bit of further fiddling with it is now producing satisfying prints. I'll show some examples below. Now obviously these are still not the quality of store-bought miniatures. For example you can clearly see the print layers. The models in brown I treated with acetone vapor, which improves the surface aspect. The others I haven't treated yet, and I'm not sure I will bother.

In the end these figurines will mostly be looked at from arm's length away, on the middle of a table on a battle map. The main requirement is that the players can tell which figurine is the beholder, and which one is the basilisk, and I think this is clearly the case here. And they are cheap: The human-sized figurines are below 5 grams of material, including losses from printed rafts and supports. The large sized ones are below 20 grams. And the material is regular ABS, costing just 2.5 cents per gram. So even a large figurine costs me less than 50 cents, while a store-bought Reaper Bones human-sized figure costs $3.
