About this 3D model

In case you want your own custom TrackMaster bridge support using MegaBloks, this adapter works pretty good. I used Inventor to design this, and for whatever reason I have to set the printer software to Inch and then scale X10 (I have to do this for everything I make). So be sure to double check the size before you print. Just for reference, the top section which accepts the track is 2.231" x 1.07".
