Hello!
I can make 3D model of the gun in Solidworks (2016 or 2018 version) with all necessary details. After I can convert model in whatever format you need, so you could easily import it into another programs or produce it.
I have 9 years of experience in 3d modelling and drafting. Some of my models was printed, cutted with CNC machine, used in VR. Also I have experience in prototyping.
Can you provide me main dimensions for gun?
Regards, Nade.
