Thanks Jeffs396. I was also wondering though how he got them into the 3D printer. If he made them from scratch or if he was able to scan a short bed side and then stretch it in the computer.?
Yes, those parts can be ordered directly from Shapeways. I chose that "Frosted Ultra Detail" as a material because it's most accurate and needs less sanding & filling. So even this "Ultra Detail" material still isn't 100% perfect. Some filling & sanding is needed.
I 3D-modeled those parts by myself. I just took the most important measurements from those short parts. So no scanning. I'm using Rhinoceros 3D-program.
