Lego Plates 4x8 for Train Ramps

Basically I took the 4x8 plate originally created and removed the top knobs to make them flat because I wanted bigger flat pieces to use at train crossings.

One STL file is a regular lego size piece at 3.2mm in height and to have a level train crossing you still need to put plates underneath.

The other STL file, I made a abnormal size so it emulates two plates together (6.4mm) so that you have a level train crossing in just one piece to make life easier.
