These are the 3D model of many kind of pipe joints/ fittings. There have 20 different pipe fittings.
I used blender 3.4.2 software to make this models.
The blend file is very clean and every single part of the joints are in different collections with their name, The models are colored with materials. So you can easily access them.
If you are using any different software, Than just download any other version I added. Such as, fbx,obj,glb,stl etc.FBX and GLB are properly textured/colored.
So just buy and enjoy the good 3D models.
