Scully printed perfectly, looks great, no issues. But Mulder will not print. I have over a dozen with missing parts, mostly feet. Did every type of orientation, messed with all my settings to be sure, all other files printing without issues, but not this one. There must be a fault in the file. STL are hallow, with eyes and teeth and other items inside, not solid. Wrote designer about getting a solid printable version. Got no reply. Tried taking it into Meshmixer to correct myself, but the file crashes Meshmixer. No idea why, no other files do that. An STL that won't print is worthless.
