Thanks, that was probably one of the most aggravating parts of the entire build lol. I was originally going to bend the styrene tubes, but that failed and I wasted a tube, then I spent a week trying to find the correct elbow to fit it, and then when I found them, waited another 2 weeks for them to arrive lol. Apparently 1/2" styrene tubes are not very common for building custom models. Spent $11 in shipping for 2 little $1 elbows. I had a few other people say they like the stacks as well, so I'm glad people like them.
