Finished printing and assembling the second set of tracks. only had to print 60 because i had some left over when i printed 80 the first time. about 60-70 per side.

Because i undersized the holes i had to drill each side out and i tapped the inside holes to make it easier to screw in the machine screws. plastic self tapping may be easier? but i had 4x40 1" screws already to use.
