I've shortened the legs a bit and thickened some of the bones. Also fused a few joints together in places to increase stability and filled the ribcage to make it a solid piece. A few of the more fiddly bits I removed completely. mz4250's original model was anatomically correct because it was based on a real horse skeleton - this model is no longer an accurate replica of a horse, but it still looks close enough for a mini, and this version takes less support, prints faster, and is more solid when done.
