Inspired by the z-scale christmas design of @Aspengt, I did make my own design for a Marklin train 760 diameter circle. The outer green and inner white are 15 degree in fase and bond to one. I did not use any glue so far. Its nice hanging in the tree supported by the branches.
You need 12 parts each and did print the outer green with uneven surface 0,1 mm pitch 0,8mm. Both models need to be printed in upwards postion with a small 3mm brim space 0,1mm.
MK4S outer green 2h50m , inner white 1h51m. Also printed on a XL and CoreOne. Single prints for clean parts.
Enjoy printing
