I'm afraid Shapeways have recently increased their prices on WSF models. This is the same model as my HO Pup/Calf LPG trailer, but has been requested by several S-scale modellers. Look for the S-scale Twin and Tri-axle LPG tankers too. Take a look at the HO versions to see actual 3D printed models. As with my other 1/64 scale models, I have not included the wheels as there are far better detailed parts available from other manufacturers.
