PCB-3D is selling out products via Fastspring payment processing system. PCB-3D Models is a project started by electronic engineers from Novi Sad, Serbia. They realized that modeling circuit boards is much easier and less time consuming if you have footprints with related 3D models set up first, they have decided to share the 3D model components they have created and that is how PCB-3D started.
Hardware projects, electronics and interest in 3D modeling has inspired PCB-3D team to constantly improve the database of PCB-3D Models. Visit their website at http://www.pcb-3d.com for PCB 3D Models, Altium Footprints, they also have tutorials and 3D CAD Models by Categories.
