I'm quite a fan of the Berserk manga, so I decide to make my own 3D printed Guts. Took me a few month (I spend 1- 2 hours a day to work on this project while I'm on lunch break with my crappy laptop), mostly trial and error, re-print with the right setting and work on zbrush to make the mesh printable without any support,
I sell the STLs here, you can pay what you want.
