That's some nice work Jasonc!
I went through several revisions with mine, trying to get the drape of the tent and the opening just right. I did try to integrally print the paracord or cables or whatever Hikaru used to string the thing up with. It didn't work very well and cleanup of the print would have been a nightmare. My final solution: thin strands of PLA, pulled by hand directly off the printer's nozzle. I cut the 8 best looking ones to length and glued them to the tent perimeter, and then to the central cable that was part of the tent part. The bundle of cables at the top was a little bit messy, but it's hidden behind the Valkyrie's head as it crouches over the tent anyway.
I made mine using tinkercad, so it was ultimately a pretty simplistic design, but if anyone wants more info on the tentl or the little LED "campfire" just ask!
