I made a Behir for my own miniature collection for d&d use and I thought I'd share it since I know how hard is to come by. If you like it and you can afford it, tips are appreciated.
The sculpt is approximatively 93 x 80 mm wide and 54 mm tall, its made to be a huge creature but, of course, you can rescale it to fit your purpose. There are two models, one solid, for general printing purpose and one hollow, for SLA, DLP printing.
I haven't printed it yet but I will pose pictures of it as soon as I do. If any of you here do print it before me, pictures are welcomed, I'm always curious to see how other people manage the prints. Enjoy and have fun!
Edit: I uploaded smaller STL files. The ones with the "A" termination are smaller but I'm unsure of their units. Zbrush makes smaller STL files but also seems to mess up the sizing.
