Ticket to Ride trains tray Free 3D print model

One of last year's Featured items on Thingiverse was a nice Ticket to Ride Locomotive Tray by princeofwands (http://www.thingiverse.com/thing:23695), which was updated and improved this year in HunterGreen's even nicer Ticket to Ride Rack design (http://www.thingiverse.com/thing:129016). However, both of those designs use a lot of plastic and take a long time to print. Today we designed a version in Tinkercad that uses far less material and prints in about half of the time, based loosely on the concept of our previous H-Tree Dish (http://www.thingiverse.com/thing:170257). http://makerhome.blogpost.com
