This is a multi part curve designed to let you create very fast turns for hot wheels cars. There are 3 parts for both the entry and exit taking the degree bank from
Part 1: 10 - 20
Part 2: 20 - 35
Part 3: 35 - 45
Part 4: 45 - 45
Each of the part and it's mirror are in the stl file you will want to split the parts in your slicing software.
I printed these in petg as it is traditionally a touch more flexible than PLA, the brittleness of PLA can lead to snapping and that can suck if your tolerances are too tight.
Each part takes of 22.5 degrees of a 500mm inner diameter circle. So using 2 of part 4 would be 45 degree bank of 45 degrees, depending on your speeds and center of gravity of the cars you may need to then print the 35-45, it is designed to be flexible for the amount of turn you would like for your tracks.
Each part also easily fits in the middle of the ender 3 bed. My previous 180 turn barely fit on the ender 3 pro bed. Each part of this print easily fits now.

Quick note you do need 2 of the 45 degree turn to make it a full 180.
