This is one of many variants I built of Necromunda ash-waste hovels.
It's about 70mm high at the roof, meaning about the size of the original necromunda building wall sections. For true 25mm models, it can be reduced by about 20%.
It still takes many hours on high resolution to print (around 30), even though it's very thin walled. On draft quality it takes around 8. I'd do that; after this model is drybrushed, rusted and painted with graffiti it'll look just fine.
Do use a brim or raft.
