Blackwidow molded in Rhino 3D with T Splines. This model is water tight with no naked edges and all surface topology is clean and all detail is build in to the model. File is ready to be imported in to another software such as Solidworks.
I have included TS (T Splines) file and it can be opened in TS Elements or any software with T Splines plug in.
Render was done in Octane and scene is included.
I have also included other file formats. Please keep in mind that the meshes are not not optimized but are highly detailed.
