About this 3D model
Brio or Ikea train track compatable train track turntable. 3 way and 4 way. the printer I use is not large enough for the 4 way turntable, so I will try and re design so that it will clip together somehow. OK I have redesigned the 4 way turntable so that you can print on a smaller table like the MakerBot 2x. use the connectors http://www.thingiverse.com/thing:15165 to connect the two halfs of track together.
