Gravitrax compatible height tile

Once you have used enough Gravitrax tiles and rails, you will run out of height tiles to continue building. This is when my custom-made Gravitrax height tile comes into play. It has a height of 10mm and 5mm respectively. Fusion 360 files is for you to make changes with it.

Note: When I tried to shell the 5mm version, Fusion 360 shows an error so I have to move onto the next step and now the final design of the 5mm height tile doesn't have an open-shell design.
