I have started printing the Infield Walls. Takes just over 8 hours to print 3 sections.







The Blue marks the straightaway.


Looks good to me so far.


I use a TPU ring at each joint to allow the material movement between the parts as they expand and contract with the weather.

So for now I just keep printing wall sections.

Note: The Oval will run counter clockwise and the Road Course will run clockwise.
