2 Lane Banked Splits and single lane banked turns

This is a collection of Files for a 2 lane to split two single lane tracks with a 15 degree bank. The single lane return would need to be mirrored to print both a right and left side returns. this could be used to print a double loop where the central line is a 2 lane drag strip and then splits into 2 single lane banked turns to return the cars to the start. This was inspired by the Mini4wd Reddit discussion of drag racing mini4wd cars. With this setup both lanes would be the same length, cars can return to the start and the banked angle should enable the cars to keep higher speeds. The turn out and the single lane returns are provided with solid and cutout versions to allow for faster/lower cost printing, or a more solid print.
