I'm sure the person with this tire and wheel IS NOT selling these items as a master, but as a finished product (check the drop-down for surface/finish options). I was just stating that the FINISHED 3D PRINTED prices are still too high for the average modeler to buy for a build.
Now if this person was to sell his design file to a caster for reproduction in resin, that's a different story, leaving the prices reasonable for the builder (like Joseph has done with his AWESOME Vector wheel ).
