Hello Sir, I have been working with 3D printing for the past few months and I have a few models printed already. I can show you only one, because they are not mine. If you contact me, I can show you them in chat. I cannot post them. I work in 3D Studio Max and then I make the models printable in Autodesk Meshmixer, which is a nice tool.
Waiting for your contact,
Best regards,
Leandro Correa
