Lecso

Unfortunately it didn't work, it filled the hollow parts, but created new holes and i didn't lost some deteal, i lost a lot... 😕

I downloaded a model of this character, it is made of multiple parts, so you can make different poses with it. I'm not familiar with this kind of 3D modelling, I've only used CAD programs before. I want to make it 3D printable but when I export it, my slicer can't slice it properly and I have no idea what to do with the model to make it work. Does anyone have an idea what should I do? Here's a link to the model. And here's google drive link for my posed version too.
