I designed this part after i printed a part that "looked" right but was not. I was able to design this from scratch with Tinkercad using the original for the key measurements.

V. 1.1 Thinned down 3 of the tubes, Corrected an error in the roof tube. I will print tonight for final fit and finish

V. 1.2 Smoothed tubes inside and out

V. 1.3 Added tube spring latch holes

V. 1.4 Added support between the three roof tubes

V. 1.5 Shortened all 3 roof tube to be closer to the original

This design has been tested for fit with the original pipes and tarp that came with the kit. Works Slick! The roof tube supports act as extra hanging / tie down locations, I am very happy with this thing!
