Crossing and Rail Pieces for Go! Go! Smart Wheels

Increased height of existing model to accomodate our version of the Go! Go! Smart Wheels train. Reduced the size of the retention clip to keep tracks together, they should still hold firm but not break when trying to remove sections from each other.

Track pieces are a great way to use up filament ends, plus kids usually love all the colours!

Also included a simple 4 way intersection piece for expanding your track. STEP files included for easier remixing and modding. Thanks to @wahnby_147576 for including original FreeCAD file.
