As we suspected, another 3D print service has added Tinkercad integration into their interface. Shapeways joins i.Materialise as an option for printing your 3D models developed in Tinkercad. Tinkercad is a web-based, very easy to use 3D solid modeling tool.
The addition of a Shapeways interface permits direct 3D printing capability, very similar to what you'd experience in word processing software. Well, the print may take a couple of days to get to you, but the software experience is very similar.
The question is, does this mean Tinkercad is now the King of web-based 3D modeling tools? What about 123d? Will they add print service connections as well?
